By no means I wanted to suggest that people should use the latest and greatest - just wanted to reason about the possibility that the screen maybe unable to share its info.
If you install read-edid and then run: sudo get-edid to find if you get any screen info on any I2C buses. If you do see info - decode it and see what the monitors are reporting.
It works like this:
sudo get-edid ... sudo get-edid -b 8 | parse-edid 8 ... Section "Monitor" ... # inxi -Sy System: Host: ab250 Kernel: 5.14.14-3-default x86_64 bits: 64 Desktop: Trinity R14.0.11 Distro: openSUSE Tumbleweed 20211207 # whoami root # get-edid This is read-edid version 3.0.2. Prepare for some fun. Attempting to use i2c interface Looks like no busses have an EDID. Sorry! Attempting to use the classical VBE interface Illegal instruction (core dumped)
