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?
You will most likely have to run wayland to get the most out of your new monitor (in a dual monitor setup), other than that should work just fine.
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…
Moving from Mint to Tumbleweed probably solved your issues because of the huge leap in kernel/driver/software versions. The default settings could have been different too, but I’m guessing it had more to do with more up to date software.
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?
Ah perfect this is exactly the vouch I was looking for. Thank you

I have two monitors (2K, 144hz, DP) and a TV (4K, 60hz, HDMI) and it ran fine on Plasma. I used X11, because my 2060 was causing issues with Wayland.
How did you deal with scaling with 2 different resolutions on X? I never managed to get it working quite properly, the closest I got was running some xrandr scale commands on login.
That’s one aspect I have to use a workaround. Since I mostly watch video on the TV, I seldom need to scale the screen. When I want to use the TV exclusively, I have a small script that shuts off the monitors, changes scaling, panels and audio output.

Do games work ok at that resolution?

I am currently using a high refresh rate monitor with Nvidia + Wayland + KDE Plasma and it works out of the box without any setup 👍
Same for me with my two monitors 1440x2560p 144Hz & 2560x1440p 165 Hz.
I got my bootup scrolling text to only display on the main monitor, but can’t get the boot down text to stop displaying on both (sideways on the vertical one). Anyone got any tips for that (besides just turn the monitor off 😂)?
I use Arch btw
No. I run 3x 1440p 144Hz monitors with KDE Plasma on an NVIDIA 1060 GTX, no issues at all.
Let me tell you.
I’m running a GTX 1050ti and I’m facing black screen and constant crashes in KDE Plasma when using Wayland.
X11 is working fine.
It might be a driver issue with nVidia on Wayland though.
My laptop has a 2560x1440, 165Hz monitor built in. I am using opensuse tumbleweed with plasma. When I attach a 1920x1080, 60Hz external monitor through my kwm switch, I have no issues. It has an Nvidia GPU, but I believe plasma is running on the integrated GPU. I don’t know if I have tried gaming or anything that uses the Nvidia GPU while using the external monitor. I mainly use the second monitor for coding.
Thanks everyone for the replies. I now feel confident in buying a new monitor. 😌

Are you using display port or HDMI? Depending on the monitor HDMI can’t support the higher output.
I can use either or. If display port was required I can use that.
I ran into that with my ASUS monitor. The HDMI protocol won’t support 2k@165hz
