[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.

Late to the party, had no solutions myself anyway, just wanted to say thank you OP for including the solution in the post.

Do you have another monitor to test with?

[–] pirat@lemmy.ml 4 points 1 month ago (1 children)

Not currently but I think I can track one down.

[–] Gnugit@aussie.zone 5 points 1 month ago

Or TV?

[–] communism@lemmy.ml 3 points 1 month ago

Could try resetting the BIOS by leaving the CMOS battery out?

[–] Grass@sh.itjust.works 1 points 1 month ago

that's definitely a new one for me

[–] Gnugit@aussie.zone 1 points 1 month ago (1 children)

Have you tried changing the bios resolution?

[–] michaelmrose@lemmy.world 8 points 1 month ago

This normally isn't a thing.

Regarding the solution: does 1.4 work fine once you're in the OS?

[–] bobo1900@startrek.website 1 points 1 month ago

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?
