Hello, I cant seem to find any upto date info on this topic and all the old threads seem to suggest that these features do not work well on linux.
I am looking to get a 144hz monitor that is at least 2k in resolution. I have an Nvidia graphics card and KDE Plasma. I want to run two monitors and the 2nd monitors is 60hz and 1080p. Would this cause issues? Is there anything I need to consider when looking for a monitor?
I ran three monitors on an RTX 3060 on Linux before and it worked fine, 1080p 144hz, 1440p 144hz, and a 1080p 165hz. Worked fine on both KDE Plasma and Gnome, didn’t try any other desktop environments.
There is something with X11 where desktop compositing runs at the framerate of the lowest hz monitor that is active, but that doesn’t affect anything when the compositor is disabled like games, and on Wayland it doesn’t have the issue. It’s not particularly a big issue either since it’s just the desktop animations and stuff, and it’s very likely to go unnoticed at all unless you’re watching for it.
