Question about High Refresh Rate Monitors and High Res Monitors on linux

Linux@lemmy.ml – 45 points – 10 months ago

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?

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.
