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).
