Question Input not supported

[sasaas]

I use two acer SB220Q monitors and suddenly after turning my computer on I get a floating box saying "Input Not Supported". If I borrow a different monitor from a friend and use that as a display there isn't a problem and once I get past the sign in screen I can switch back to the other monitors and they work just fine as long as I don't have to restart my pc. I made sure that my pc resolution was the same as the monitors but it still wont work. I'm running windows 11 if that makes any difference.

Welcome to the forums, newcomer!

When you're on your own monitors, are you able to get into BIOS without any issue? If you can't see anything, use the donor panel, get into OS GUI, use DDU to uninstall your GPU drivers, then shut down, disconnect from the wall and display as well as the internet, then reconnect to the older panels, power up, manually install the latest GPU drivers in an elevated command(while being offline).

For greater context, please list the specs to your build like so:
