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).

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

      Of course, was grateful for everyone sending ideas, I eventually was tooling around in my. monitor settings to see I’d I could reset something.

      I just started going with my general philosophy of ‘what does this do?’ and flip back if something undesirable / unnoticeable happened.

      was honestly shocked when I stumbled upon it as I don’t recall switching the input version for the monitor.

    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.

    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?

      I was able to fix by changing the input version on the monitor (though I don’t recall switching it).

      This all happens before the OS / graphics driver loads.

      so initial mobo splash, grub, and bios if I enter that screen.

      I think so unless it does a switch at some point. I’ll take a look and update when I’m on the CPU later today.
