Hi!

My setup is:
1. Motherboard: ASRock X670E Taichi.
2. CPU: Ryzen 9 9950X.
3. Video Card: Gigabyte RTX 3080 Vision OC.
4. Monitor: ViewSonic VP2768-4K (27", 3840x2160p, 10-bpc)

Annoyance:
The resolution of the UEFI/BIOS menu is 1024x768.
The BIOS menu offers 2 options:
1. "Disabled" = 1024x768
2. "Auto" = 1920x1080.
However, whether I choose "Auto" or "Disabled", the resolution remains the same, at 1024x768.

I've connected the monitor to the video card, both, through a DP 1.4 cable & an HDMI 2.1 cable.
No change!

I've taken out my video card directly to the HDMI port of my motherboard, because the CPU has an iGPU.
No change!

I have set "Disabled" & restarted PC.
Then set "Auto" & restarted the PC.
No change!

A.I. tells me something about the GOP driver which locks my UEFI menu at that low resolution.

ANY IDEAS ???
