The monitor might be flashing the EDID when powered on to fix situations where the EDID might have corrupted itself. I think the best solution is to use an EDID emulator like this:

I don't think that emulator is writable, but you can use CRU to get the correct resolution in Windows while having 1080p supported during boot.

Thank you for your thoughts and suggestions, ToastyX.

Here, in my country, the EDID emulators are a good portion of the cost of a new monitor, so it may be better to invest in a new screen. I plan to do that eventually. The motherboard's BIOS is definitely a culprit, and I have noticed that others having similar problems tend to be using MSI.

I will submit the issue to Intel (and perhaps MSI), and hopefully, they can further polish their firmware, helping others down the line. When I'm ready, I'll buy a new monitor.

Many thanks for your time and assistance. Have a pleasant day!

Very cool to see this released — thanks for sharing, ToastyX! Having a proper tool for writing EDIDs and DisplayIDs directly is huge for testing and repair work. Appreciate the warning about the EEPROM risk too — definitely not something to mess with casually.
