I have been running 4k resolution over HDMI 2.1, now it’s screwed.
What I did:
I was changing the configuration options for a game in Lutris. Under: Configure-System Options- Change resolution
I thought this was going to force change the resolution in game, except it force changed my desktop resolution. My monitor is kind of finicky to begin with and it never changed to whatever resolution I selected (I think 1080p). It just fails to receive input and the monitor goes black.
Now I need to use Display Port connection to use the PC, which defaults to 4k. But if I try to use HDMI, same problem. Even after restarting PC with HDMI, it will display BIOS, encryption login, even the Manjaro login, but as soon as it gets to the desktop- fails… like it’s trying to display the 1080p still everytime but fails.
So I’m thinking there must be a config file or way to change the selected resolution for my HDMI connection?
Help please.
