== External Inputs, Outputs, and Ports ==

=== Front Panel Functions ===
[[File:Morph_4K_Base_Unit.png|thumb|right|400px|Example of Morph's Base Unit visualized from the front and rear panels]]
All Morph 4K's are constructed with a front physical power switch (off/on), an LED indicator, IR sensor, microSD port, and 6 navigation buttons.

==== Physical Switch, LED Indicator, and IR Sensor ====

Power Switch - Physical power switch. Push to the right to turn the unit on and to the left to turn it off.

LED Indicator - Light emitting diode that glows or flashes in various colors to communicate various statuses to the user. The front LED will glow light blue when the Morph is powered on and working normally. 

LED Colors and Meanings:

* Blue for initial boot, then goes to color in Morph Setting (Blue by default, yet can be customized to match OSD Colors)
* White for [[Morph_4K#Remote_Control|standby mode via the remote's power button]]
* Enters color sequence during [[Morph_4K#Method_A._Flash_Morph_with_MicroSD_Card|SD card flashing]] (Red blinking x2, Green blinking x5, Yellow blinking continuously, turns White when finished)
* Red blinking x2 continuously for WiFi access point as part of [[Morph_4K#Rescue_System_via_WiFi|Rescue System via WiFi]]

G.E.M. Specific:

* Breathing = HPD (hot plug detection) waiting for connection or installation issue on the 5v rail
* Solid = connection established
* Blinking = error -> check installation; check if the correct jumpers are closed on the GEM -> try flashing the FW again and reformat FS while doing so

IR Sensor - Detects [[Morph_4K#Remote_Control|button presses]] by the included IR remote and can also be used to [[Morph_4K#Custom_IR_Remote|customize additional remotes in the WebUI]].

==== MicroSD Port ====

A microSD card must be inserted (printed side up) at the front of the unit, next to the front panel buttons. This is used to [[Morph_4K#Presets|manage presets]], [[Morph_4K#Updating_Firmware|flash firmware]], [[Morph_4K#Write_debug_log|write a debug log]], and store other related files.

* '''Must be in FAT32 or exFAT format'''
* Storage amount can be as low as 4GB (''custom presets may demand more storage so consider between 8GB and 32GB to be on the safe side'')
* Formatting tools:

==== Navigation Buttons ====

The face buttons on the front of the unit can be used to navigate the Morph 4K's on-screen menu.  This is useful in situations where an IR remote is not available.  The face buttons also have various context sensitive functions that are documented elsewhere.  From left to right the buttons are:

* Circle button - Open on-screen display, enter sub-menus, confirm choice. This is the same as pressing [[Morph_4K#Remote_Control|OK on the remote]].  This button can also be used to perform a [[Morph_4K#Method_A._Flash_Morph_with_MicroSD_Card|manual flash with the microSD]] or initiate the [[Morph_4K#Using_the_Rescue_System|rescue system]].
* Square button - Go back or cancel choice. This is the same as pressing [[Morph_4K#Remote_Control|Back on the remote]].
* Up button - Navigate upwards in a menu. This is the same as pressing [[Morph_4K#Remote_Control|Up on the remote]].
* Down button - Navigate upwards in a menu. This is the same as pressing [[Morph_4K#Remote_Control|Down on the remote]].
* Left button - Decrease a value or navigate left in a menu. This is the same as pressing [[Morph_4K#Remote_Control|Left on the remote]].
* Right button - Increase a value or navigate right in a menu. This is the same as pressing [[Morph_4K#Remote_Control|Right on the remote]]. This button can also be held for 5 seconds to perform an [[Morph_4K#Emergency_1080p_Reset|emergency 1080p reset]].

=== Rear Panel Connections and Power via Base Unit ===

Morph 4K's base unit includes 4 ports: USB-A, HDMI IN, HDMI out, and USB-C.  Even with the ability to expand more rear connections, these 4 ports are included on every unit.

==== USB-A Port ==== 

Morph 4K's base unit has 1x USB port at the rear. This port is currently unused, but will be used in future to control AV switching hardware such as the [https://docs.pixelfx.co/infinity-switch.html Infinity Switch] (to be released).

==== HDMI In ====

The HDMI input port is located directly to the right of the USB port. The port is rated for the HDMI 1.4a standard and will accept up to 1080p video at 60 frames per second with a 4:4:4 color space.  

Morph 4K's base unit has 1x HDMI input only.  For HDMI equipped consoles, such as Xbox 360, PS3, or consoles with an internal HDMI upgrade (RetroGEM), Morph 4K can accept these devices directly or in combination with an HDMI switch.

For devices that output an analog signal, Morph 4K can be [[Morph_4K#Rear_Panel_Connections_Expanded_via_Analog_Bridge_and_Crosspoint | expanded with two module types that accept analog inputs]] and this allows the HDMI input port availability for dedicated HDMI devices.  Alternatively, Morph 4K can accept a second analog to digital scaler (i.e. [https://junkerhq.net/xrgb/index.php?title=OSSC OSSC]) as an "analog bridge" over the HDMI input port.

An orange LED will appear when Morph detects an active HDMI input.  The LED turns off when HDMI input is no longer detected.

==== HDMI Out ====

The HDMI output port is located between the HDMI input port and USB-C power connector.  The port is rated for the HDMI 2.0b standard and is capable of outputting up to 4K video at 60 frames per second in 4:4:4 color space.  The port can also passthrough Dolby Digital (DD) & Digital Theater Systems (DTS) audio formats.

==== USB-C Power Connector ====

Standard USB-C power connector.  Morph's base unit requires a 5V power supply with at least 1.5A of current.  With analog expansion cards (bridge/crosspoint), Morph will require a 5V power supply with at least 2.5A of current (3A recommended). 

Note that many phone chargers may not provide consistent current and a dedicated power adapter is recommended. 

A Raspberry Pi 4, 15W USB-C Power Supply is recommended. (Output voltage: 5.1V, Output current: 3.0A, Output power: 15W)

=== Rear Panel Connections Expanded via Analog Bridge and Crosspoint ===
[[File:Morph_4K_Analog_Connector_Cards.png|thumb|right|400px|Example of Connector Cards from top to bottom: SCART & Component, VGA & Component, and VGA & VGA]]

Morph 4K can be expanded with a pcb module that adapts a row of analog connectors.  There are two modules, an Analog Bridge and an Analog Crosspoint (to be released).  The differences between these two modules is in the manner in which they handle analog ports.  The Analog Bridge covers two analog input ports whereas the Analog Crosspoint covers one analog input port and one analog output port.  The analog ports come as Connector Cards and are offered in three flavors for each module: SCART & Component, VGA & Component, and VGA & VGA.

'''Note:''' ''Custom made Connector Cards can be generated using a [https://github.com/citrus3000psi/BLANK_CARD blank card template created by citrus3000psi].''

'''Note:''' ''To use the dedicated composite video input on the dual VGA bridge, you need to choose "Input Port B -> Composite Video over GREEN".''
[[File:Jumpers_for_VGA_port.jpg|thumb|right|250px|||Example of 5-6 and 7-8 jumpers bridged for audio over VGA port]]
==== Jumpers ====

The SCART and VGA ports on the analog connector cards have a bank of 4 jumpers for audio that can be bridged using a 1.27mm jumper (e.g [https://www.mouser.com/ProductDetail/Harwin/M50-1900005?qs=hQdOagyNhkvFZChZOhb1qQ%3D%3D Harwin M50-1900005]). The pins on the jumpers should be connected from top to bottom.

Most SCART and VGA adapter audio configurations are reserved for future use.  However, if you wish to use the [https://github.com/citrus3000psi/SCART2VGA SCART2VGA adapter created by citrus3000psi] to convert the VGA port on a connector card into a SCART-to-VGA bridge, be sure to bridge the 5-6 and 7-8 jumpers.

== Basic Setup & Usage ==

Connect your Morph's HDMI output port to an HDMI compatible TV or monitor using an HDMI cable. Remember to use a cable rated for 4K video (at least HDMI 1.4 for 4K 30Hz or HDMI 2.0 for 4K 60Hz) if using a 4K display. 

Connect an HDMI source to the HDMI input port of Morph and ensure a suitable power supply is linked to the USB-C connector.  Turn on Morph using the physical power switch at the front left of the unit.  Verify your TV or monitor is set to the correct input to receive Morph's HDMI output port. You should now see a "No Signal!" message on your TV or monitor. Turn on the HDMI source and within milliseconds, Morph will display it on the TV or monitor.

=== Remote Control ===
[[File:Morph_4K_Remote.png|thumb|right|400px|Default button mappings for the Morph remote]]
Morph ships with a basic IR remote control. If desired, a more advanced remote control can be used instead, either via IR or CEC. Remote control through WiFi is also possible once WiFi setup is completed. See [[Morph_4K#Remote Control Setup|Remote Control Setup]] for more information.

The remote control requires 2 x AAA batteries, these are not included due to postage service restrictions. Insert 2 x AAA batteries into the remote (IR remotes have a low power draw, so rechargeable batteries are perfect) and press the "Menu" button (house icon) to toggle the Morph's menu on or off. 

The included remote uses the following buttons as of the current firmware. More functionality may be added in future firmware updates.

* Red Power Button - This button will toggle Morph in and out of standby mode while remaining powered on via the physical switch (as of firmware 3.2.11).  
** When entering standby mode, the front LED will turn white.  Neither Morph's on-screen menu nor HDMI input source will be displayed on the TV or monitor.  If the HDMI input source is still detectable, Morph's rear LED will remain orange.  Morph's WebUI is still available, yet features are limited.
** When exiting standby mode, the front LED will briefly turn pink for a few seconds and then change to blue (or if you're on firmware 3.7.6 and set a new default LED choice via the RGB selection in the on-screen menu) to indicate Morph is awake and fully functional.  Morph's WebUI is fully available.

* Menu or Back buttons - Two buttons (one with a house and one with a return arrow) acts as a Menu or Back button. This button will toggle Morph's on-screen menu on or off. If you navigate to a submenu option, the button will take you instead to the previous menu. Keep pressing the button to navigate back to the main menu and then again to close the menu.

* Navigation buttons - Use these directional controls to navigate through the main menu, submenus, and to change any operational values.

* OK button - The OK button in the middle of the navigation arrows can be used to enter submenus and confirm changes for an operational value. Remember to press OK if you wish to make a change to any value.  If you press the Menu or Back button, the changes will be discarded.

* Shortcut buttons - The colored shortcut buttons at the top of the remote perform various functions depending on the submenu.  Throughout this wiki, you will see them referenced as '''<span style="color:red">red</span>''' / '''<span style="color:green">green</span>''' / '''<span style="color:#FFDB58">yellow</span>''' / '''<span style="color:blue">blue</span>''' shortcut buttons.

* Reset to Default button - The button with a left arrow and X in the center will reset a value to default within submenus.

=== Setting Up Morph === 

If you have a WiFi connection available, it is recommended to setup the WiFi connection and check for any firmware updates. Morph is a new product and regularly receives new firmware updates. See the [[Morph_4K#WiFi|WiFi]] and [[Morph_4K#Updating Firmware|Updating Firmware]] sections for more information.

Your next step should be to check that Morph is outputting the most suitable resolution for your TV or monitor. Navigate to "Video" on the Morph's on-screen menu and them to "Output Resolution".

Use the remote to select the desired resolution then press "OK". If your display cannot accept the chosen resolution, Morph will reset to the previous resolution after 30 seconds. If your display is unable to accept a 4K signal from Morph, despite being rated for 4K use, please check that your HDMI cable is rated for 4K.

Usually you would choose the highest resolution that your television can support. Typically for a 4k television, you would choose "4K" as the output resolution. However, if you want to use the Black Frame Insertion feature (Insert data) you would choose "1080p120" instead. 

You are now ready to start exploring Morph's functionality. For an overview of what you can do with various sources, proceed to the next section.

== Console Connection Basics ==

Morph can accept and process signals from a huge range of games consoles, computers and even video equipment. The focus of the Morph is for scaling and processing video games although it can also be useful in some instances for processing video material too. Below is an overview of different types of consoles, how they connect to the Morph and how you might wish to process them with the device.

=== Pre-HDMI Gaming Consoles and Computers ===

This category encompasses all games consoles before the seventh generation, and some seventh generation machines such as the Nintendo Wii and the original launch Xbox 360. Typically these machines will connect to the Morph in one of three ways.

* With an internal HDMI upgrade (RetroGEM) or an external adapter
* With [[Morph_4K#Using a Second Scaler as an Analog Bridge|a second scaler as an analog bridge]]
* With an expansion module fitted to the Morph 4K's base unit

Using either a good quality HDMI upgrade or adapter or the dedicated analog expansion card on the Morph will yield the best results.  However, utilizing a secondary scaler (such as an [https://junkerhq.net/xrgb/index.php?title=OSSC OSSC]) can also produce excellent results.

To connect using a HDMI upgrade, HDMI adapter or secondary scaler, use the adapters "pass-though" or "digitization only" mode if one is available. If no passthrough mode is available, choose the lowest output resolution offered by the adapter/scaler and then use the "Prescale" options under the "Scaler" menu on the Morph to effectively undo any scaling the adapter applies. 

For specific considerations for each system, see [[Morph_4K#Compatibility_and_Special_Configuration|Compatibility and special configuration]] 

'''What can the Morph do for Pre-HDMI consoles and computers?''' These machines were typically designed for older displays (especially sixth generation and earlier systems). Morph 4K can properly scale and process these systems and add CRT effects such as scanlines, to make them look as pleasing as they did on legacy CRT displays. For systems which output interlace video (e.g PS2) Morph 4K has a fast, motion adaptive deinterlacer that is optimised for video game content.

=== Seventh and Eighth Generation Consoles and Gaming PCs Up to 1080p ===

Systems such as Nintendo Wii-U, Xbox 360 (later revisions) PS3 and gaming PCs from this era typically output up to 1080p/60 via digital/HDMI connections. The Nintendo Switch would also fall into this category.  Systems like PS4 which can output higher resolutions and/or HDR have special considerations and will be discussed in the next section.

'''What can the Morph do for these systems?''' These machines were typically designed for more modern displays, however the Morph gives you more control over both 1080p and 720p scaling and can produce better results than the scalers that are built into many displays.

Systems such as the PS3, Xbox 360 and Nintendo Wii-U/Switch, which frequently or primarily target 720p, can be upscaled by the Morph to produce either a significantly sharper or smoother image depending on the users preference.

Emulated titles or pixel art style games titles on these platforms (e.g Virtual Console) can be reprocessed by the Morph to correct bad scaling or to add scanlines or CRT filter effects.

=== Eighth and Ninth Generation Consoles and Modern Gaming PCs ===

Modern video games consoles and PCs output higher than 1080p resolution. These resolutions cannot be directly processed by the Morph. If you wish to use these systems with the Morph, without limiting their output capabilities, then you will need some way to split or switch their output so that you can bypass the Morph. Remember that many HDMI splitters or switches are not compatible with variable refresh rate that these systems can use. 

Many PC graphics cards offer multiple monitor outputs, so in this case it is easy to connect one monitor output to the Morph and the other directly to the display.

'''What can the Morph do for these systems?''' Emulated titles or pixel art style games on these platforms can be reprocessed by the Morph to correct bad scaling or to add scanlines or CRT filter effects.

== Using a Second Scaler as an Analog Bridge ==

The Morph 4K can be placed between your display and an existing scaler to instantly upgrade your setup with 4K scaling capabilities.  This is an ideal option for anyone who is already happy with their existing analog switching/scaling solution and just wants a simple, low hassle upgrade path to 4K.

For best results with your existing scaler, set the unit to output in "Passthrough" or "Digitisation Only" mode.  This will allow the Morph 4K to handle all of the scaling and will produce the best results.  If your existing scaler does not support this, use 480p output mode instead and use the [[Morph_4K#Scaler|Scaler menu]] to set a /2 vertical prescale on the Morph.  Be aware this may mean that your existing device also deinterlaces 480i/576i content, meaning the Morph cannot use it's own deinterlacer.

Some HDMI switches may not support 240p via HDMI. In this case, you can use 480p mode instead and a 2x vertical prescale.

The following devices have a passthrough mode that can be used with Morph 4K:

*[https://junkerhq.net/xrgb/index.php?title=OSSC OSSC Classic] - Activate passthrough mode by following the instructions [https://junkerhq.net/xrgb/index.php?title=OSSC#Passthru_mode here]
*[https://junkerhq.net/xrgb/index.php?title=OSSC_Pro OSSC Pro] - Use in pure or adaptive line multiplication mode, then configure the same as OSSC Classic
*[https://junkerhq.net/xrgb/index.php?title=RetroTINK-2X RetroTINK-2X Classic]
*[https://www.dropbox.com/s/ftbncaowx1ps1of/RT2X%20Pro%20Manual.pdf?dl=0 RetroTINK-2X Pro] - Set the Mode switch to "Pass".
*[https://consolemods.org/wiki/AV:RetroTINK-5X_Pro RetroTINK-5X Pro] - Activate downscaling mode by following the instructions [https://consolemods.org/wiki/AV:RetroTINK-5X_Pro#Downscaling here]

Be aware that in passthrough mode, clock and phase adjustments will work on the OSSC Classic/OSSC Pro, but optimal presets (256x240, 320x240 etc) require firmware 1.10 (OSSC Classic) or greater.

The following devices do not have a passthrough mode and require prescale conditions to use with Morph 4K:

* RetroTINK-2X SCART - Use 2x vertical prescale
* [https://junkerhq.net/xrgb/index.php/XRGB-3 XRGB-3] - Use B1 mode for minimal lag and 2x vertical prescale
* [https://junkerhq.net/xrgb/index.php?title=XRGB-mini_FRAMEMEISTER XRGB Mini Framemeister] - Either use 480p output (and 2x vertical prescale) or 720p output (and 3x vertical prescale) depending on preference

'''Note:''' ''When using these devices, if you do not set the prescale, scanlines will not be drawn correctly. See [[Morph_4K#Scaler|Scaler menu]] for more information.''

=== Advantages ===

*Cost - By making the most of your current investment, Morph 4K gives you the lowest possible cost for 4K retro gaming scaling.

*Ease of installation - Few changes should be required to your current setup to integrate Morph 4K. Any existing analog switching hardware can be reused.

=== Disadvantages ===

*Added lag - Frame buffer based scalers may introduce lag, this lag will be added to your video chain. Line multipliers generally do not add lag so this disadvantage would not apply to those devices.

*Inherent flaws of some scalers cannot be mitigated - For instance the XRGB Mini Framemeister is known to add noise to some signals, this will still apply when using it with the Morph 4K, of course.

*Resolution changes will still incur a delay - Scalers like the XRGB Mini Framemeister has a very long delay between switching between 480i and 240p content, this will still apply when using the unit with the Morph. Line multipliers like the OSSC and RetroTINK-2X Pro work much better because the Morph will actively keep the connection with your display while it waits for the line multiplier to resync. However, the dedicated analog bridge will still perform slightly better in this regard.

*Remote control - Morph 4K cannot remotely control your existing scaler, for example to select a different input. Using an alternative remote control with custom programmed IR commands could get around this limitation.

== On-Screen Display (OSD) Main Menu and Submenus ==

[[File:Morph_Menu_Navigation_Image.gif|thumb|300px|right|Scrolling Morph's main menu]]

Morph 4K offers an on-screen display (OSD) navigation that allows you to change various operational values before or during gameplay.  From the main menu, the following choices are available:

* [[Morph_4K#Presets|Presets]]
* [[Morph_4K#Input|Input]]
* [[Morph_4K#Video|Video]]
* [[Morph_4K#System|System]]
* [[Morph_4K#Restart|Restart]]
* [[Morph_4K#RX_Input_Analyzer|RX Input Analyzer]]
* [[Morph_4K#TX_Info|TX Info]]
* CEC remote

=== Presets ===

The Presets menu is found at the top of the main menu.  Presets act as the identity profile to apply Morph 4K settings based upon input sources and other conditions.  This menu can be used to create profile presets, manually load profile presets, automatically load profile presets, and keep the [[Morph_4K#MicroSD_Port|microSD]] card up-to-date with the preset archive.

By default, you can add mask presets and color correction profile presets in the <code>.ini</code> or <code>.txt</code> file extension to Morph from your PC by manually placing them on the microSD card in the '''presets''' subfolder visible in the file explorer or through the [[Morph_4K#SD_Card_.2F_Presets|SD Card / Presets manager in the WebUI]] by placing them in the ''/sdcard/presets'' directory.

From the Preset menu, you have the option to download the latest [https://github.com/pixel-fx/morph4k-presets preset archive] of community profile presets, [[Morph_4K#Retro_FX|mask presets]], and [[Morph_4K#Color_Correction|color correction profile presets]] directly to Morph with a WiFi connection via '''Install/update from presets archive'''.  This archive will automatically store on the [[Morph_4K#MicroSD_Port|microSD card]] and will only overwrite profile presets with matching names and folder paths.

Since many consoles with analog outputs have multiple resolutions and switch between interlaced and progressive scan (e.g. 240p/480i), Morph's profile presets decimate and shift the horizontal and vertical lines from the analog signal before Morph upscales it for the display.  Whereas for consoles with built-in HDMI, they can send a uniform digital signal to Morph with little to no adjustments.  In special circumstances, consoles with built-in HDMI may require a profile preset to assist with downscaling their digital signal before Morph upscales it (e.g. Analogue Pocket in Integer mode or Nintendo Classics on NSO).  However, there are no profile presets in the archive that apply to Retro GEM (or xDigital) since the device is already equipped to send a raw digital signal via direct modes (DV1-Direct / DV1-Passthru / FX-Direct).  Direct video is also available on MiSTer FPGA via HDMI (direct_video=1) and it's advised to apply this mode when connecting a MiSTer to Morph.  In the event MiSTer in DV1 has issues with HDMI switches into Morph, then consider the MiSTer 1080p prescale profile presets as a backup option.

Also, profile presets are capable of [https://docs.pixelfx.co/Morph4K-Preset-Autoload-cascaded.html automatically loading] based on detection of CEC, Game ID, Mode, and SPD.*  All of these appear under the ''/sdcard/presets/Auto'' folder in the following structure:

* '''/By_CEC*''' - For consoles or devices that communicate over CEC protocol (''such as Nintendo Switch's Match TV Power State option'')
* '''/By_Gameid*''' - For any consoles or devices that can provide Game ID details
* '''/By_Mode*''' - For standard HDMI or analog device detection

=== Input ===

The Input menu is for choosing your input source.  On Morph's base unit, the HDMI input is the only input source available and this has a few input settings available.  When an [[Morph_4K#Rear_Panel_Connections_Expanded_via_Analog_Bridge_and_Crosspoint|Analog Bridge and Connector Card]] are installed, the input sources appear as follows.

* '''Port A'''
* '''Port B**'''
* '''HDMI'''
[[File:Morph_Input_Menu_Navigation.gif|thumb|300px|right|Setting Morph's input to Port B]]
Contained within Port A and B is a submenu to choose the analog input type.

* '''Composite Video over GREEN''' ''(CVBS green)''
* '''Composite Video over HSYNC''' ''(CVBS hysnc)''
* '''S-Video'''
* '''Component (YPbPr)''' ''(YCbCr)''
* '''RGB(HV/S) (TTL sync levels)''' ''(RGB TTL)''
* '''RGB(S) (75 ohm sync levels)''' ''(RGB 75)''
* '''RGsB (sync on green)''' ''(RGsB)''

After the correct analog input type is chosen, then Morph will display the active analog source along with various input settings.

'''**''' ''Since Port B accepts multiple input connections, be sure to power on a single analog input at any given time on Port B.  This is to avoid crossing frequencies when multiple inputs are active over a shared port.''

=== Video ===

The Video menu is comprised of submenus that allow you to change various settings that affect the Morph's scaling and color capabilities.  The submenus are as follows:
[[File:Morph_Video_Menu.png|thumb|300px|right|Contents of Morph's Video menu]]

* [[Morph_4K#Scaler|Scaler]]
* [[Morph_4K#Morph_4K#Shift_.2F_Crop|Shift / Crop]]
* [[Morph_4K#Deinterlacer|Deinterlacer]]
* [[Morph_4K#Smoothing|Smoothing]]
* [[Morph_4K#Retro_FX|Retro FX]]
* [[Morph_4K#Color_Correction|Color Correction]]
* [[Morph_4K#Output_Resolution|Output Resolution]]
* [[Morph_4K#Advanced_Video|Advanced Video]]

==== Scaler ====

The scaler menu contains options that directly affect the prescale of the image.  This allows Morph to correct or discard any existing scaling that might have been applied to the image and then apply its own scaling.  For example, if you feed the Morph 4K a pre-scaled 240p image from a device such as a RetroTINK SCART, that image is already scaled to 480p by the RetroTINK. To un-do this scaling, set the vertical prescaler to /2. The Morph 4K will then apply its pre-scaling settings and scanlines will be spaced in the same interval as on a classic CRT television. 

For more information, [https://www.youtube.com/watch?v=dKhJrT_h1cY See this video] for a demonstration of using a /3 prescale with a Framemeister set to 720p output.

|-
|style=width:10em | '''Zoom'''
|For zooming the image to the required size. By default, this adjusts based on the Aspect Ratio set to Auto, yet you can adjust the increment gradually by 0.004 using the '''<span style="color:#FFDB58">yellow</span>''' or '''<span style="color:blue">blue</span>''' shortcut buttons or by 0.250 (coarse) using the left or right navigation on the remote.
|-
|'''Aspect Ratio'''
|For adjusting the proportional relationship between an image's width and height via the display aspect ratio (DAR) and pixel aspect ratio (PAR).  By default, this is set to '''Auto'''.  Many retro gaming consoles use a 4:3 aspect ratio, while most modern consoles and devices use 16:9 aspect ratio.
|-
|'''Horiz. Interpolation'''
|For adjusting the sharpness of the horizontal scale.  Leaving this set to '''off''' applies a nearest neighbor interpolation.  Additional options available that are forms of bilinear: '''softer''', '''soft''', '''sharp''', '''sharper''', or '''sharper (alt)'''.
|-
|'''Vert. Interpolation'''
|For adjusting the sharpness of the vertical scale.  Leaving this set to '''off''' applies a nearest neighbor interpolation.  Additional options available that are forms of bilinear: '''softer''', '''soft''', '''sharp''', '''sharper''', or '''sharper (alt)'''.
|-
|'''Horiz. Prescale'''
|For reducing the horizontal prescale factor starting from '''/1''' all the way to '''/32'''. Can be used to correct bad scaling applied by the connected system. Known as "Input Decimation" on some other scalers.  By default, this is set to '''Auto'''.
|-
|'''Vert. Prescale'''
|For reducing the vertical prescale factor starting from '''/1''' all the way to '''/32'''. This is typically used with pre-scaled content or pixel art video games to create a more accurate scanline presentation.  By default, this is set to '''Auto'''.
|-

==== Deinterlacer ====

Deinterlacing is the process of converting interlaced video to progressive video. Modern fixed resolution displays cannot display interlace video directly, and this content must be deinterlaced first, either by the deinterlacer built into the display or an external device, such as the Morph 4K.

[[File:Morph_Deinterlacer_Menu.png|thumb|300px|right|Example of Morph's Deinterlacer settings]]

{| class="wikitable" align="center"
!Setting
!Details
|-
|style=width:10em | '''Field Order'''
|Refers to the order in which each pair of video fields is processed. Some systems may present interlace content as "Upper" or "Field 2 drawn first". Change this setting to '''Inverted''' if you know your target system does this, otherwise leave it set to the default choice, '''Normal'''.
|-
|'''Method'''
|Choose which method of deinterlacing to use.  By default, this is set to '''Motion Adaptive'''.  All deinterlacing options are as follows: <br> &nbsp;&nbsp; - '''Bob''': Also known as line doubling, takes the lines of each interlaced field (consisting of only even or odd lines) and doubles them, filling the entire frame <br> &nbsp;&nbsp; - '''Blend''': Creates frames by by averaging lines from the two most recent, can produce ghosting effects <br> &nbsp;&nbsp; - '''Weave''':  interleaves consecutive fields together into a single frame, can cause combing artefacts <br> &nbsp;&nbsp; - '''Motion Adaptive''': Uses an algorithm to determine the best deinterlacing solution for each part of the image <br> &nbsp;&nbsp; - '''Simulate CRT''': Uses Bob deinterlacing but also more closely simulates how a CRT displays interlace content by alternating the scanlines
|-
|'''Sensitivity'''
|Change the sensitivity of the motion detection algorithm for the deinterlacer in order to fine tune it for your source material. Lower values may result in combing artefacts on object edges.
|-
|'''Interpolator'''
|Selects how pixels detected as having motion are processed. Only available when the deinterlacer is in motion adaptive mode. <br> &nbsp;&nbsp; - '''Upper field''' or '''Lower field''': use bob deinterlacing offset either up or down <br> &nbsp;&nbsp; - '''Average''': linearly interpolates the bob output to make the offset less noticeable
|-
|'''Detector'''
|Configure how the motion detector works. Only available when the deinterlacer is in motion adaptive mode. <br> &nbsp;&nbsp; - '''Zero-lag''': Detects motion based on past video fields only <br> &nbsp;&nbsp; - '''Symmetric''': Buffers 1 field additional field to allow for more accurate motion detection at the cost of slightly more input lag
|-
|'''Noise threshold'''
|This setting prevents small changes in the image (which could be attributed to picture noise) from influencing the amount of measured motion in the image. Increase this value for noisy sources, decrease for clean sources such as HDMI direct.  It can be incremented by 1 using the left or right navigation or by 10 (coarse) using the '''<span style="color:#FFDB58">yellow</span>''' or '''<span style="color:blue">blue</span>''' shortcut buttons on the remote.
|-
|}

==== Smoothing ====

Use the options in this menu to apply an additional smoothing algorithm to the image beyond the softness/sharpness interpolation in the Scaler submenu.  Use of smoothing filters is usually a matter of personal taste.  You may prefer to use them for all content, exclusively for older 3D content, or not to use them at all.  The effects are comparable to the smoothing done by devices such as the [https://marseilleinc.com/ Marseille mCable].  However, Morph 4K gives you significantly more control over the final image.  There are currently two algorithms available:

{| class="wikitable" align="center"
!Algorithm
!Details
|-
|'''XBR'''
|Scale by rules (XBR) is an edge detection smoothing algorithm that was designed originally for pixel graphics.  It aims to give retro graphics a more natural, hand drawn look without sharp pixel edges. [https://forums.libretro.com/t/xbr-algorithm-tutorial/123 See this page for more technical information.]
|-
|'''HQX'''
|High quality scale (HQX), also known as high quality magnification, is a set of efficient image upscaling algorithms developed by Maxim Stepin.  Like XBR it aims to give retro graphics a more natural, hand drawn look without sharp pixel edges. [https://en.wikipedia.org/wiki/Hqx See this page for more technical information.]

==== Retro FX ====
[[File:Morph_Retro_FX_Menu.png|thumb|300px|right|Example of running (re)scan presets to detect all 611 masks newly added to the microSD from the [[Morph_4K#Presets|preset archive]] and allow them to be selectable]]
The Retro FX menu is where you apply scanlines and masks. Since Retro gaming consoles were designed around cathode ray tube (CRT) displays, Retro gaming video content looks more authentic (and therefore subjectively better) when presented with simulated picture effects that mimic the characteristics of these displays.

{| class="wikitable" align="center"
!Setting
!Details
|-
|style=width:10em | '''H. + V. Scanlines''' <br> ''' - Saturation''' <br> ''' - Strength''' <br> '''- Thickness/Glow'''
|Horizontal and vertical scanline options are set to '''Off''' by default.  These can be set to '''On''' or '''On (alt)''' to draw a basic scanline.  It can also be set to '''Adaptive''' to draw a scanline that simulates bloom or thickness where the image is brighter.  All values can be incremented by 1 using the left or right navigation or by 10 (coarse) using the '''<span style="color:#FFDB58">yellow</span>''' or '''<span style="color:blue">blue</span>''' shortcut buttons on the remote. <br> &nbsp;&nbsp; - Changing the saturation boosts the brightness of the scanline uniformly across the whole brightness range. Turning up this setting too high can result in clipped highlights in exchange for overall brightness.  <br> &nbsp;&nbsp; - Changing the strength adjusts the maximum width of the scanline effect. <br> &nbsp;&nbsp; - Changing the thickness (basic) or glow (adaptive) adjusts how much the thickness or bloom effect will change at bright points on the image.
|-
|'''Mask''' <br> ''' - Type''' <br> ''' - Intensity''' <br> '''- Transform'''
|The Morph 4K can also emulate sub-pixel "Mask" effects such as [https://en.wikipedia.org/wiki/Shadow_mask shadow masks] or [https://en.wikipedia.org/wiki/Aperture_grille aperture grills]. These are most effective at 4k output resolutions. Some mask effects are designed to work with scanlines applied too, while others will look better when used in isolation.  Toggle the Mask option on or off to apply mask emulation. <br> &nbsp;&nbsp; - For type, choose your desired mask. Morph comes with several masks via the [[Morph_4K#Presets|presets archive]] and more masks can manually be created via the WebUI.  When new masks are added to the microSD, pressing the '''<span style="color:blue>blue</span>''' shortcut button will (re)scan presets and accumulate all new masks as selectable options.  <br> &nbsp;&nbsp; - For intensity, you can adjust how intense or pronounced the mask effect is on the image either incrementally by 0.01 using the left or right navigation or by 0.10 (coarse) using the '''<span style="color:#FFDB58">yellow</span>''' or '''<span style="color:blue">blue</span>''' shortcut buttons on the remote.  <br> &nbsp;&nbsp; - For transform, you can rotate or flip the mask effect.  Options are: '''Multiply by 2''', '''Rotate 90''', '''Rotate 180''', '''Rotate 270''', '''Mirror Horiz.''', '''Mirror Vert.''', '''Flip NW/SE''' (Northwest/Southeast), or '''Flip NE/SW''' (Northeast/Southwest).
|-
|}

If applying masks or other post processing effects causes your TV or monitor to add a strange tint to the image or display in what appear to be the wrong colors, then it is likely that your display is not processing the full 4:4:4 color space. The errors in color are due to chroma subsampling. [https://en.wikipedia.org/wiki/Shadow_mask This page on rtings.com explains it in more depth.]

To force your TV to process the incoming image with full color bandwidth, you may need to set it to PC mode. This is done on some sets simply by renaming the input to "PC" or choosing PC as the device type. Ensure you are using high bandwidth HDMI cables too. 

The test pattern [https://www.rtings.com/images/test-materials/2017/chroma-444.png available here] allows you to quickly test if your display is using full 4:4:4 color bandwidth. If any of the text on the image is not pin sharp, then your display is applying chroma subsampling.

==== Color Correction ====

The Color Correction submenu is used for Morph 4K's HDR injection and Gamma adjustments.
[[File:Morph_Color_Correction_Menu.png|thumb|300px|right|Example of Morph's Color Correction settings]]

{| class="wikitable" align="center"
!Setting
!Details
|-
|style=width:10em | '''HDR***'''
|Injects High Dynamic Range (HDR) metadata.  HDR refers to the set of imaging technologies and techniques that allow the dynamic range of images or videos to be increased.  Typically this refers to the difference between the darkest and the brightest parts of the image.  The technology is used to render bright or dark scenes more accurately.  HDR can also be used by the Morph to boost display brightness, typically to add in brightness that is often lost when using effects such as masks or scanlines.  The following options are available: <br> &nbsp;&nbsp; - '''Disabled''': No HDR metadata injection is performed <br> &nbsp;&nbsp; - '''Off (with CSC)''': No HDR metadata injection is performed but color correction controls are available for use within the standard definition image <br> &nbsp;&nbsp; - '''HDR10''': An open high-dynamic-range video (HDR) standard <br> &nbsp;&nbsp; - '''HLG''': Hybrid Log Gamma - A standard jointly developed by the BBC and NHK for high dynamic range (HDR) display <br> Generally you should choose whichever mode works best on your display. Displaying SDR content within a HDR gamma curve will cause colors to be displayed incorrectly. The Morph has various controls to correct and compensate for this.
|-
|'''Color Profile'''
|Use this to load a saved color correction profile preset from the microSD card, either from the [[Morph_4K#Presets|preset archive]] or manually generated thru the [[Morph_4K#Web Interface|WebUI]].  Click right on the remote and select it under ''/sdcard/presets/Color Correction (CSC)''.  Then click OK to apply.
|-
|'''Input Gamma''' <br> '''- Transfer Function''' <br> '''&nbsp;&nbsp; - Factor''' <br> ''' - Gain''' <br> ''' - Lift''' <br> '''- Bit Crush'''
|For adjusting the gamma curve as it is converted from the SDR gamma curve to the HDR gamma curve.  Transfer functions available are Gamma, sRGB, SMPTE-240M, or Rec.709, and each has the option of adjusting the factor from 1.0 to 3.0.  The input gamma's gain and lift can be adjusted along with the bit crush, set to off by default, by a scale from 1 to 7.  Increasing the input Gamma may compensate for brightness lost when applying scanlines and/or masks, but care must be taken not to increase gamma too high and crush bright white parts of the image.  Values can be incremented by 0.01 using the left or right navigation or by 0.10 (coarse) using the '''<span style="color:#FFDB58">yellow</span>''' or '''<span style="color:blue">blue</span>''' shortcut buttons on the remote.
|-
|'''Color Space Conversion''' <br> ''' - Overflow''' <br> '''- Saturation'''
|For adjusting the color space conversion as it is converted from the SDR to HDR.  Overflow can be set to attenuate or clip along with saturation of the color space.

==== Output Resolution ====

Morph comes packaged with a set of 5 display resolutions.  It is best to choose the highest resolution supported by your display. The exception to this is if you wish to utilize black frame insertion (BFI), in which case a 120hz display mode is best capable of handling the inserted black frames without affecting image quality.  The current output resolution has an exclamation point ('''!''') to the right.  When choosing a new resolution, you must press the OK button once to confirm and then again to save the change.  If you do not save the change within 20 seconds, Morph will revert to the previous screen resolution.

Additional resolutions can be added through the [[Morph_4K#Custom_Modelines|custom modelines option in the WebUI]].

==== Advanced Video ====

Options in this menu affect the output of the Morph 4K's video.

{| class="wikitable" align="center"
!Setting
!Details
|-
|style=width:10em | '''Frame Lock'''
|Engaging frame lock syncs the input refresh rate exactly with the output refresh rate. This usually results in the smoothest possible image movement/scrolling and the least amount of input lag. By default, this is set to '''Off (triple buffered)'''.  All options are as follows: <br> &nbsp;&nbsp; - '''Off (triple buffered)''': Disables frame lock, which will uncouple the input and output frame rates. Turning off frame lock is essential for games which change between resolutions, such as 240p and 408i, as it will allow the Morph to re-sync the image as fast as possible. <br> &nbsp;&nbsp; - '''Normal''': Syncs the input refresh rate exactly with the output refresh rate, buffers a small number of lines so that picture parameters such as zoom can still be adjusted without causing an image re-sync <br> &nbsp;&nbsp; - '''Minimal (lowest lag)''': Sets the minimum amount of buffering for the very lowest lag possible, yet you will lose the picture temporarily if you try to adjust the image zoom or aspect ratio
|-
|'''Triple Buffer'''
|Changes the output frequency as long as Frame Lock is set to Off (triple buffered).  By default this is set to '''Auto (50/60hz)''', yet can be set to '''Force 60Hz''' for NTSC input or '''Force 50Hz''' for PAL input.  If you encounter a game title that has image drop outs between levels or loading screens, even when using Triple Buffer mode, try forcing the appropriate refresh rate rather than using the default setting.
|-
|'''BFI'''
|Black frame insertion (BFI) causes every other frame to be black.  This can improve motion clarity on some displays, at the expense of some image brightness.  It is most useful when coupled with [[Morph_4K#Output Resolution|120hz output resolution]] and [[Morph_4K#Color_Correction|HDR injection]].
|-
|'''Color Space'''
|Toggles the output color space.  By default, this is set to '''auto''', yet can be changed to '''limited''' for 16-235 levels of brightness or '''full''' for 0-255 levels of brightness.  Full range RGB is very common for computer monitors and PCs while limited range RGB is usually used for video devices such as DVD players. Managing this difference in brightness levels across various devices is often challenging when the device sends incorrect EDID information to invalidate the selected color space.  Auto is recommended for most setups, yet the setting may need to be changed in some cases.
|-
|'''AVI IF ITC/CN'''
|IT content (ITC) and content type (CN) are two variables of the Sink Auxiliary Video Information (AVI) InfoFrame (IF).  Basically, this field allows the disabling or selection of the content type field in the AVI IF.  By default, it's set to '''Game'''.  There are other options for media content ('''Cinema''', '''Photo''', '''Graphics''') or it can be '''Disabled'''.  Switching it to something other than '''Game''' is necessary if your TV may be processing the signal differently as per HDMI/ANSI CTA-861-I spec.
|-
|'''Inject VFR-EMP'''
|Variable Frame Rate extended metadata packet (VFR-EMP) injects a flag or extra data packet on the HDMI signal to tell the display to expect a variable refresh rate image. Currently, this does nothing more than add the VFR/VRR flag to the signal, which has been shown to help some TVs when handling off-spec refresh rates. The available options are: <br> &nbsp;&nbsp; - '''Disabled''': Do not send VRR metadata packet at all. This is different from "off", since no VRR metadata is sent whatsoever to the display <br> &nbsp;&nbsp; - '''Off''': Sends a metadata packet to the display to explicitly disable VRR <br> &nbsp;&nbsp; - '''Auto''': Sends the appropriate VRR metadata packet based on the connected display EDID <br> &nbsp;&nbsp; - '''Vesa''': Send a metadata packet to the display to tell it to expect a VESA standard VRR signal <br> &nbsp;&nbsp; - '''Freesync''': Send a metadata packet to the display to tell it to expect a AMD Freesync VRR signal
|-
|'''RX DV1/FXD'''
|Enables or disables detection and autoscaling of native DV1 metadata (~240p/480i) from [[MiSTer_FPGA|MiSTer FPGA]] and [[Direct_Video_Info|PFX Digitals/GEMs]].  For some MiSTer cores, this may require the use of [[MiSTer_FPGA#DV1_Config_Files_for_MiSTer_Cores | DV1 config files]].
|-
|'''RX Input CS'''
|For setting the input color space of the HDMI source.  By default, this is set to '''Auto''', yet in some cases may need to be changed.  The setting appears greyed out when the input signal isn't HDMI.  For example, if the input signal is DV1, then RX Input CS has no effect because DVI is always RGB full range by definition.  The following options are available: '''Auto''', '''Auto (no ITC)''', '''RGB AVI Limited2F''', '''RGB Limited''', '''RGB Full''', '''YCbCr 601 Limited''', '''YCbCr 709 Limited''', '''xvYCC 601''', '''xvYCC 709''', '''YCbCr 601 Full''', or '''YCbCr 709 Full'''.
|-
|'''RX 422 Interp.'''
|For HDMI sources with 4:2:2 chroma subsampling, turn this option '''on'''. Otherwise, leave it '''off'''.
|-
|'''RX EDID'''
|For setting the Extended Display Identification Data (EDID) detection of the HDMI input source.  The default option is '''default.bin''' and for most sources, this is the best option to use.  Yet in certain cases, another EDID may be required.  Options are as follows: '''h-dac.bin''' ''(for Analogue consoles like Mega Sg, Super Nt, and Analogue Pocket Dock)'', '''a-dac-ntsc.bin''', '''a-dac-pal.bin''', or '''2ch-pcm-only.bin'''.  Advanced users can also use this option to [[Morph_4K#EDID|select a custom EDID file]].
|-

=== System ===

The System menu is comprised of submenus that allow you to keep Morph up-to-date with the latest firmware and configure various functional settings.  The submenus are as follows:
[[File:Morph_System_Menu.png|thumb|300px|right|Contents of Morph's System menu]]

* [[Morph_4K#WiFi|WiFi]]
* [[Morph_4K#Firmware|Firmware]]
* [[Morph_4K#OSD|OSD]]
* [[Morph_4K#Morph_Settings|Morph Settings]]
* [[Morph_4K#SD_Card_Info|SD Card Info]]
* [[Morph_4K#Game_ID|Game ID]]
* [[Morph_4K#EDID|EDID]]
* [[Morph_4K#Debug_.2F_Self_Test|Debug / Self Test]]
* [[Morph_4K#Snake|Snake]]
* [[Morph_4K#Info|Info]]

==== WiFi ====

Morph includes an ESP32 chip with WiFi capability**** over a 2.4 GHz band (802.11 b/g/n).  This allows you a few great features, such as the ability to easily check for firmware updates and [[Morph_4K#Updating_Firmware|update the firmware]].  It also expands access to Morph's [[Morph_4K#Web_Interface|Web Interface]], offering a [[Morph_4K#WiFi_Remote_Control|wireless remote control]] option and customizations.

In order to connect WiFi for the first time, you will need to run '''Start Setup Wizard''' to take you through the [[Morph_4K#WiFi_Setup_Wizard|WiFi Setup Wizard]].  Once Morph has established a connection to your router, then the following fields are always present:

:* '''SSID''' will show the router's 2.4 GHz SSID
:* '''Ch/SigQ''' will show the router's 2.4 GHz channel value (1, 6, or 11 preferred), signal quality strength from Morph to the router (better if at least ~50%), and that the state is Connected
:* '''Hostname''' will show Morph's default hostname [http://morph4k.local/user.html.gz morph4k.local] for accessing the [[Morph_4K#Web_Interface|Web Interface]]
:* '''IP''' will show Morph's assigned IP address from the router (either a 192.168.x.x address or different depending on router settings)
:* '''MAC''' will show Morph's unique MAC address (can be used to identify it on the router)
:* '''Web user''' and '''Web pass''' are hidden credentials to access the [[Morph_4K#Web_Interface|Web Interface]] and can be revealed using the '''<span style="color:red">red</span>''' shortcut button on the remote

If the above fields look incorrect, then you may want to double-check the [[Morph_4K#Router_Compatibility|router's settings]] to ensure Morph can establish a stable connection with the 2.4 GHz SSID.  You may even need to restart Morph or proceed through the [[Morph_4K#WiFi_Setup_Wizard|WiFi Setup Wizard]] once more.

Additionally, you can open the '''Station Settings''' submenu to customize connectivity with three settings.
[[File:Morph_WiFi_Menu.png|thumb|300px|right|Example of WiFi submenu with a connection as well as the Disable credentials setting is set to yes]]
{| class="wikitable" align="center"
!Setting
!Details
|-
|'''Auto Connect on Start'''
|For Morph to connect over WiFi as soon as its powered on, this setting is best kept on.  If you prefer to manually manage the WiFi connectivity, then turn this off.  Then you can use the '''<span style="color:green">green</span>''' shortcut button on the WiFi submenu to Disconnect WiFi.
|-
|'''Minimum RSSI required'''
|For adjusting the Received Signal Strength Indicator (RSSI) of Morph's ESP32 antenna.  This limits connectivity with routers over a wider distance as the detected signal quality strength will be considerably less.  By default, this is set to 40% (-80dBm), yet this can be as low as 20% (-90dBm) and as high as 80% (-60dBm).  In rare cases would you ever set this above 40% (-80dBm).  To maximize compatibility with further routers, keep this at the lowest setting, 20% (-90dBm).
|-
|'''Disable credentials'''
|For turning off the web user and web pass credentials required to access the [[Morph_4K#Web_Interface|Web Interface]].  By default, this is set to no.  For ease of access to the WebUI, set this to yes.
|-
|}

'''****''' ''The ESP32 is configured to support WiFi only.  There is no support for Bluetooth.''

==== Firmware ====

The Firmware submenu is used to manage firmware updates either downloaded directly to Morph over a [[Morph_4K#WiFi|WiFi]] connection or accessible from your [[Morph_4K#MicroSD_Port|microSD]] card.  It is comprised of a few operations:

{| class="wikitable" align="center"
!Operation
!Details
|-
|'''Release Notes'''
|Allows you to view release notes on the selected update channel starting from the most recent firmware version to the earliest and contains list details for new features, fixes, and/or general improvements.  If you prefer to view these release notes on a PC or mobile device, they can also be accessed from [https://firmware.pixelfx.co/ https://firmware.pixelfx.co/].
|-
|'''Update Channel'''
|The Morph has several update channels which may contain the same or different firmware versions. By default, the '''Stable''' channel is selected.  Each update channels is described below.<br> &nbsp;&nbsp; - '''Stable''': This channel contains firmware that has been thoroughly tested and proven to be suitable for general use <br> &nbsp;&nbsp; - '''Testing''': This channel has firmware that may contain new features still in development with minor bugs or errors <br> &nbsp;&nbsp; - '''Unstable''': This channel has firmware that may contain new features heavily in development and not yet thoroughly tested so bugs or errors can appear
|-
|'''Check for Update'''
|Allows you to run a firmware version check against the PixelFX server on the selected update channel to compare the staged and installed firmware versions.  When these values are equal, then you will see the message "Firmware is up-to-date."  When these values are not equal, then you can click OK to check release notes for the version differences and either click back to exit or click OK to initiate a firmware update.  For the full list of steps to implement the firmware update, check out [[Morph_4K#Updating_via_WiFi|Updating via WiFi]].
|-
|'''Update Firmware*****'''
|Allows you to stage and install the newest firmware update available from the PixelFX server based upon the selected update channel.  For the full list of steps to implement the firmware update, check out [[Morph_4K#Updating_via_WiFi|Updating via WiFi]].
|-
|'''Update Firmware from SD Card'''
|Allows you to install firmware from the microSD card.  For the full list of steps to implement the firmware update with a microSD card along with alternative methods, check out [[Morph_4K#Updating_via_SD_Card|Updating via SD Card]].
|-
|'''Select Alternative Firmware'''
|Allows the user to change the FPGA firmware on the fly.  A standard firmware update installs new firmware for the ESP32 and FPGA through a full installation process. This option allows you to change just the firmware FPGA file in a few seconds.  While no alternative firmware are currently available, in the future this functionality will allow the user to keep alternative FPGA firmware on the [[Morph_4K#MicroSD_Port|microSD]] card and change between them without needing to do a full firmware installation.
|-

|Allows you to change the font, or typeface, used across all menus and submenus.  By default, this is set to '''iso.font'''.  Other font choices are as follows: '''default.font''', '''display.font''', '''fancy.font''', '''font2.font''', '''iso88591.font''', and '''tremolo.font'''.
|-
|'''Endless menu'''
|Allows menu and submenu cursors to move from top to bottom of the screen continuously through remote navigation input without impediment.  By default, this is set to off.
|-
|'''Endless FB'''
|Allows menus and submenus file browsers (FB) to wrap around long file name text rather than cutoff the file name due to length. By default, this is set to off.
|-
|'''CEC'''
|Allows Morph to be detected and controlled via by TV or monitor remotes and other devices that support Consumer Electronics Control (CEC).  By default, CEC is enabled and is a useful way to [[Morph_4K#Remote_Control_Setup|control Morph with another remote]] out of convenience.  In some cases, this may cause interference with certain TV remotes and need to be disabled.
|-
|'''Version Check'''
|Allows Morph to check for check for a new firmware update automatically and display a notification.  [[Morph_4K#WiFi|WiFi]] must be setup and connected for this to work.  By default, this is set to check '''once''' every power cycle, yet can be turned off or set to check '''always'''.
|-
|'''Notifications''' <br> ''' - Animation''' <br> ''' - Timeout'''
|Allows you to customize the animation speed and timeout length of any firmware or system notifications.  Speed and timeout can be incremented by 1 using the left or right navigation or by 10 (coarse) using the '''<span style="color:#FFDB58">yellow</span>''' or '''<span style="color:blue">blue</span>''' shortcut buttons on the remote.  Any changes can be saved and tested using the '''<span style="color:red">red</span>''' shortcut button on the remote.
|-
|'''Screensaver'''

|style=width:10em | '''LED''' <br> ''' - Red + Green + Blue'''
|Allows you to customize the color of the physical LED visible from the front panel using a hexadecimal color value scale (0-255 / 0x00-0xff).  By default, Red is set to '''000 / 0x00''', Green is set to '''255 / 0xff''', and Blue is set to '''255 / 0xff'''.  To turn off the LED completely, set all values to '''000 / 0x00'''.  Values can be incremented by 1 using the left or right navigation or by 10 (coarse) using the '''<span style="color:#FFDB58">yellow</span>''' or '''<span style="color:blue">blue</span>''' shortcut buttons on the remote.  If you need help deciding on a custom color, try a [https://htmlcolorcodes.com/color-picker/ color picker].
|-
|'''Menu''' <br> ''' - Red + Green + Blue'''
|Allows you to customize the color of the Morph banner at the top of every menu and submenu using a hexadecimal color value.  By default, Red is set to '''000 / 0x00''', Green is set to '''255 / 0xff''', and Blue is set to '''255 / 0xff'''.  Setting all values to '''000 / 0x00''' or '''255 / 0xff''' will turn the Morph banner white.  Values can be incremented by 1 using the left or right navigation or by 10 (coarse) using the '''<span style="color:#FFDB58">yellow</span>''' or '''<span style="color:blue">blue</span>''' shortcut buttons on the remote.  If you need help deciding on a custom color, try a [https://htmlcolorcodes.com/color-picker/ color picker].
|-
|'''Preset auto-load'''
|Allows you to automatically load preset files stored under the ''/sdcard/presets/Auto'' directory via the microSD card when turned on.  More details can be found under [[Morph_4K#Presets|Presets]].  By default, this is set to off.
|-
|'''Overscan marker'''
|Sets a temporary overscan region behind a visible display chosen within the [[Morph_4K#Input|Input]] menu or while using [[Morph_4K#RX_Input_Analyzer|Border Detect]].  By default, this is set to on.
|-
|'''Write debug log******'''
|Allows you to write a debug log file called ''debug.txt'' to the root directory of the [[Morph_4K#MicroSD_Port|microSD]] card. This is useful in the event you encounter a problem or issue using your Morph and need to share your debug log with PixelFX.  By default, this is set to off and can be changed to '''yes (overwrite)''' to write over the file on each power cycle or '''yes (keep)''' to continuously record lines without losing debug history.  The debug log can easily be accessed from the [[Morph_4K#Web_Interface|Web Interface]] at [http://morph4k.local/sdcard/debug.txt http://morph4k.local/sdcard/debug.txt].  Currently TX, RX and Clock events are recorded as well as other notable events.  In order to locate events in their context, you can use the '''Number 5''' button on the Morph remote to create a ''user mark'' in the log file (such as when a sync drop occurs) to assist in inspecting the debug log for unusual behavior in proximity to the recorded user marks.********
|-
|'''Signal modifier'''
|Allows you to change Morph's HDMI transmitter charge pump current. By default, this is set to off.  Turning this on is recommended when using a very long HDMI cable or when advised during troubleshooting by PixelFX support.  First check for the existing value via the [[Morph_4K#Web_Interface|Web Interface]] URL [http://morph4k.local/signal_modifier/VALUE http://morph4k.local/signal_modifier/VALUE], then replace VALUE with a different option i.e. 0, 1, 2, 3.
|-
|'''Fan setting'''
|Allows you to control the speed of a [[Morph_4K#Cooling_Fan|fan that is installed inside the Morph case]].  By default, this is set to '''full''', yet the value can be decreased on a scale starting from '''255''' down to '''0'''.  Decreasing the value is useful to reduce the speed of a 5V fan to help with noise.  However, this only works as long as the 5V fan supports reduced speeds.  When not supported, especially with 12V fans, reducing the value will turn off the fan.  It can be incremented by 1 using the left or right navigation or by 10 (coarse) using the '''<span style="color:#FFDB58">yellow</span>''' or '''<span style="color:blue">blue</span>''' shortcut buttons on the remote.
|-
|}

'''******''' ''Timestamps in the debug log file are in GMT as long as Morph is connected to WiFi (otherwise timestamps will be based on the Unix epoch (starting "Thu Jan 1 00:00:00 1970").  This will also happen for debug log entries before WiFi has been connected the first time after a power cycle. The debug logger also writes a "---- mark ----" to the log file every minute without other log activity.  It's normal to see some SCDC errors during startup or resolution changes, especially with frame lock enabled.''

'''********''' ''If you're using an [[Morph_4K#Custom_IR_Remote|alternative IR remote]] that you programmed through the Web Interface, then make sure to add this to the custom ir.ini file for the included Morph remote: <code>* command_num_5 = 0xf609</code>.''

'''Bottom Debug / Self Test Section'''

This section verifies status of the following fields.

{| class="wikitable" align="center"
!Field
!Details
|-
|style=width:6em | '''Lag'''
|Displays the lag response in milliseconds (ms).  This is useful for checking lag when [[Morph_4K#Advanced_Video|Frame Lock]] is set to minimal (lowest lag) or normal.  In minimal (lowest lag), lag will dial-in around 1ms.  In normal, lag will dial-in around 6ms.  However, if Frame Lock is off (triple buffered), then the lag will consistently fluctuate from around 16ms down to 0ms and this is standard behavior.
|-
|'''Input CS'''
|Displays the input color space (CS), which is typically '''24bit'''.  This is useful for testing color input from games that use 24-bits (8-bits each for RGB).
|-
|'''Core Temp'''
|Displays the FPGA's core temperature in both Celsius (°C) and Fahrenheit (°F).  This is useful to monitor temperature levels of the FPGA during gameplay.  Standard operation is between ~55-65°C and this can vary for Morph based on environment and airflow, etc.  When Morph's HDMI input is fed a 1080p signal, then the temperature will rise to ~70°C.  This is still perfectly healthy since the FPGA's operating junction temperature is 125°C.
|-
|'''M-Trig.'''
|Displays matrix trigonometry.  Currently only shows a '''0'''.
|-
|'''IR Address'''
|Displays the infrared (IR) address of the remote control in the form of a hexadecimal code.  This value will remain the same when pointing the remote at Morph to test, whether that's the remote that comes with Morph ('''0xfe01''') or for a [[Morph_4K#Custom_IR_Remote_Control|custom remote]].
|-
|'''Command'''
|Displays the command referenced by the IR remote control for each button in the form of a hexadecimal code.  This value will change when pointing the remote at Morph to test different buttons.
|-

'''Note:''' ''WiFi Setup Wizard saves settings on the microSD card.  Be sure to use a [[Morph_4K#MicroSD_Port|compatible microSD card and format]] before proceeding.  An incompatible microSD may cause Morph OSD to freeze during WiFi Setup Wizard.''
[[File:Morph_WiFi_Setup_Wizard.png|thumb|300px|right|Example of WiFi Setup Wizard on step 3 of the instructions when the second QR code appears]]
To setup WiFi on Morph for the first time, you will need to perform the following steps:

# With Morph powered on via physical switch, use the remote to open the main menu by pressing either the Menu button (shaped like 🏠) or OK button.
# Navigate to System > WiFi > Start Setup Wizard and then press OK on the remote to begin.
# A QR code will appear on the menu.  Use your phone's camera to scan the QR code, click on the popup link underneath the scanned QR code, and then your phone will establish a WiFi connection to Morph's wireless access point.
#* If you have trouble with the QR code, then you will need to manually change your phone's (or PC's) WiFi settings.  Select '''MORPH 4K''' from your WiFi's SSID list and enter the password ''MORPH 4K'' (all capital letters).
#* If DHCP is disabled on you phone or PC and you're using a static IP address, be sure to re-enable DHCP in order to connect to the '''MORPH 4K''' SSID.
# Once your device is connected to Morph's access point, a second popup link will appear underneath the scanned QR code.  Click on the link and it will automatically open the WiFi Setup Wizard in a browser window.
#* If this fails to open automatically, then manually open a browser window and type into the address bar [http://192.168.4.1/wiz http://192.168.4.1/wiz].
# For Select WiFi Network, a list of nearby SSIDs will appear.  Choose your router's SSID and then click Next.
# For Enter WiFi Password, type in the exact password for your router's SSID.  Click on the eye icon to the right of the field in order to reveal the password, confirm it looks correct or make any revisions, and then click Next.
# For Set WebUI Credentials, enter a username and password you want to use in order to access Morph's [[Morph_4K#Web_Interface|Web Interface]].  If you do not make changes to the fields, they will both default to ''morph4k''.  Click Next.
# For Save & Apply, confirm all of your settings look correct.  If you need to make any changes, click the Back button.  If everything looks good, then click Finish to save your settings and restart Morph.
# Confirm Morph is now connected to your router's SSID by opening Morph's main menu again and navigating back to the [[Morph_4K#WiFi|WiFi]] submenu.

=== Router Compatibility ===
If Morph fails to connect to your router's SSID, then you may need to adjust some settings on the router to ensure a 2.4 GHz band (802.11 b/g/n) is enabled.  It's very possible the router may be using default settings that can impair the connection to Morph's WiFi antenna.

In order to make these changes, you will need access to the router's administration portal.  If you own the router, then login to the administration portal with the username and password you defined during initial setup (or check the router's instruction manual for the default username and password).

'''Note:''' ''If the router is managed by your ISP, then reach out to them for assistance with changing these settings on the router's administrative portal.''

:* In the router's wireless settings, verify that Smart Connect is disabled.  Smart Connect tends to be configured automatically when using a router's quick setup method.  While it combines the router's 2.4 GHz and 5 GHz bands into a single SSID, this means the router automatically reserves the 2.4 GHz and 5 GHz on a device-by-device basis which can severely impact device compatibility if incorrectly assigned by the router.
:* If the router's 2.4 GHz and 5 GHz bands are separated, there will be two SSIDs.  Check the 2.4 GHz SSID's settings and make sure the security option is set to '''WPA2/WPA3 Personal''' or similar.  Morph's WiFI antenna supports WPA2 Personal, and including WPA3 will greatly increase your router's compatibility to accept newer devices.
:* While reviewing the 2.4 GHz SSID's settings, verify:
:** The channel is set to either 1, 6, or 11.  These are non-overlapping channels and are less susceptible to interference from nearby routers or other wireless network devices.
:** The channel width is set to 20 MHz.  If this is set above 20 MHz, there's a higher likelihood of interruption due to sharing the same network connection with other devices. 
:* If the above settings look correct, then as a last resort restart the router before going through the [[Morph_4K#WiFi_Setup_Wizard|WiFi Setup Wizard]] again
:# Unplug the power cable/turn off the router
:# Wait 60 seconds and then plug the power cable back in/turn on the router
:# Wait at least 5 minutes for the router to re-establish internet connectivity to all devices

If you prefer to connect Morph to your phone's mobile hotspot (i.e. a wireless access point that uses cellular data), then make sure it is enabled for 2.4 GHz before proceeding with the [[Morph_4K#WiFi_Setup_Wizard|WiFi Setup Wizard]].
