[SOLVED] How do I fixed my borked BIOS screen? (lemmy.ml)

I'm not sure when or how, but one day when I plugged my monitor back into the graphics port my BIOS screen looked like this.

Everything is fine when I boot into the OS.

I read that updating the BIOS could fix this, but to no avail.

Not sure what info would be relevant here but here are some basics:

ROG Strix 760-I Gaming Wifi running Version 1825 BIOS
Nvidia 4080
Kubuntu
Odessey G9 Ultrawide

EDIT - SOLUTION

Turns out the monitor was using display Port Version 1.4; when I switched this to v1.2 everything went back to normal

**EDIT - Thanks! **

I wanted to say thanks to everyone who put eyes on this and offered testing ideas, I'm glad I was able to stumbled to a solution that was prompoted by some of the ideas in here (even though the solution may not seem connected initially to anything stated).

That looks like VRAM corruption, though it's unlikely that the only ram corruption occurs in the video ram and only when the BIOS settings are on, but maybe the issue lies in the graphics adapter in that specific video mode.

Does this happen only when entering the BIOS settings? What about during POST (when the motherboard logo is on screen) or after post when the OS is loading before the graphics driver is loaded?
