[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).

Might be worth removing the graphics card and using integrated graphics to see if it does the same thing.

That looks a lot like a video card issue. If it isn’t, my next guess would be the power supply. Some of the weirdest things I have encountered were cause by a semi-functional power supply. When nothing makes any sense, borrow a power supply from somewhere just to rule out some of the really obscure cases.
