gui bootscreen resolution with opencanopy efi

All,

Background: I recently upgraded from 0.55 to 0.60 version of opencore. Along the way I decided to use opencanopy + Resources to use a GUI for boot selection. Along with the files, I use the following in the config per the OC guide.

  • Misc -> Boot -> PickerMode: External
  • Misc -> Boot -> PickerAttributes:1

The system works with a boot GUI; but resolution of the boot GUI selection screen seems to be very low (like 640 X 480 px). I use display port connection (for the 60Hz refresh rate) to my monitor from a Radeon RX 560. Latest lilu + whatevergreen kext is used.

Question: Is there a way to get the boot GUI resolution to be higher? Thanks for any valuable suggestions.
