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?
On my PC at home I’m running KDE Plasma on OpenSUSE Tumbleweed with two monitors: 1440p 240 Hz, 4k 60 Hz. Both are connected via displayport to an RTX2080. It works perfectly fine for me.
A while back, I used Linux Mint on the same system and it was a headache, where it would sometimes boot to a blank screen and I would have to restart a random number of times before it would work. I never did figure out the underlying cause, it just went away when I changed distros for other reasons…

Are you using wayland? As far as I’m aware X11 can’t handle different refresh rates for different monitors so it defaults to the lower one.
Chiming in to say #Wayland is what resolved this issue for me. I had to switch from Linux Mint Cinnamon to #EndeavourOS + #GNOME and I’m much happier with my setup now.
What’s your GPU?
X11 can use the higher refresh rate when using multiple monitors. It just runs everything at a higher refresh rate which can cause tearing on the lower one.
Ah perfect this is exactly the vouch I was looking for. Thank you
