Video Modes and Settings
480i vs. 480p
The GCHD Mk-II is able to display video native 480p progressive scan in compatible game. For non progressive scan compatible titles a linedoubled 480i picture mode is available which utilizes bob-deinterlacing.
When operating the device using HDMI, a standard HDMI cable is all that is necessary.
When running video via Wii Component, or Wii SCART, more video options become available. Inside the IR Menu, under "Other Settings" and then "Analog Out" users can switch between RGB, RGsB, yuv, and dyuv. Each of these settings will be contingent upon your display, or scaler settings for compatibility. Please note that the Mk-II does support dual video when utilizing both the Wii Component/SCART port as well as HDMI
My image is split when using component on my CRT
If you image is splitting in a way like the images below, simply turn off the line doubler in the IR menu.
My image is very pixelated when using HDMI
If you are experiencing this simply turn off "Enhanced DVI Mode" to remedy the picture, however this will remove the audio signal via HDMI. Instead you can pull audio from the 3.5mm jack or by utilizing the red and white auxiliary cables via the wii component port.
My image is displaying in the wrong colors when using my receiver
If your GCHD Mk-II is plugged into a receiver before reaching your TV, and certain display modes like 480p are displaying with incorrect colors(see images below), there is likely an issue with a mode setting on your receiver.
To remedy be sure to disable any "Video Conversion Option" that your receiver is likely using.
