I wonder if you could add a mode that used the PCD defaults and EFI_GYPH_HIGHT
and EFI_GLYPH_WIDTH to calculate the mode and not need as large a list?
f
## This PCD defines the video horizontal resolution.
# This PCD could be set to 0 then video resolution could be at highest
resolution.
gEfiMdeModulePkgTokenSpaceGuid.PcdVideoHorizontalResolution|800|UINT32|0x40000009
## This PCD defines the video vertical resolution.
# This PCD could be set to 0 then video resolution could be at highest
resolution.
gEfiMdeModulePkgTokenSpaceGuid.PcdVideoVerticalResolution|600|UINT32|0x4000000a
