Just giggled as my last meme mentioned trouble with displays and appropriately, a large chunk of the replies were “well MY displays work just fine!” (And charmingly, many were thoughts of things to check, other distros etc. It’s a very kind community, though that may also be the fediverse.)
Your meme about displays got me to go fix the 4k60 output on my PC. I use a TV as my screen and the EDID it reports us borked and leaves it off so I had to make a custom EDID and inject it at boot.
10/10 way easier than it sounds, annoyed I had to use a popular windows program to do it though because the first copy I found of the app I needed had a Trojan (thanks VirusTotal for confirming I’m not crazy for checking every exe no matter how official looking).
Why tf do we not have an EDID editor?
