Multimonitor Problems with Triple Monitor Setup

Hello Community i searched in the Forum and couldnt find my Problem because of that i create this Post.

  1. The issue

I Have the Issue that when my 4k 165 HZ Display connected is with my 2 2560x1440@144hz Displays and i want to aktivate 144hz and 165 hz My entire desktop Crashes und my My Displays are Flickering in alot of different Colors on a Black Background
2. Attempts to solve it

I have Installed Garuda OS Gaming Edition complete anew Installed the Nvidia DKMS Driver with the Linux Headers needed and tried at which point the desktop crashes if i use 2560x1440 instead of 4k on my 4k Monitor i can use all three Monitors with their Maximum Refresh Rates ( 2x 144 hz and 1x 165 HZ for my Main Monitor).

I Can use my 4k Monitor with 120 HZ if my 2x 2560x1440 Monitors are yousing 60 hz any higher than that and it crashes. i Tried to Use 120 HZ for All three Monitors and it Crashes, I Tried using Wayland did the neccesary pre work so that nvidia and wayland are Working and the same Happens i did deactivate VRR on Wayland it changed nothing.

if i Try to activate HDR for my Main Monitor the same Happens except if the 2 2560x1440 Monitors are deaktivated ( i know this doesnt Help with my Problem i just wanted to try it and the Same Problem did happen)

I Tried Windows which is Installed on another internal Drive and i have no Problems whats so ever even if i activate VRR and 12 bit Color Depth and Maximum Refresh rates on all Monitors and HDR it works perfekt because of that i think it is not a Hardware or Cable Problem.

Here iis my Garuda-inxi iutput :

this about hdr: HDR monitor support - ArchWiki

this helped me a lot to fix unresponsive/laggy desktop: 433094 ā€“ No way to disable tearing prevention

Comment #16

Also I assume you are a gamer given the setup, if you feel games being laggy despite the high fps: alt+shift+f12 to disable kde effects (search equivalent for other WM), do it again to re-enable them.

Thanks for Help with HDR, I have no Problems with a laggy desktop because i already did the changes from the post, i have no Performance Problems in Games.

Do you have any Idea why i cant use my 3 Monitors at maximum refresh Rates and resolution together ? i can use them together only if my 4k monitor resolution is set to 2560x1440@120hz instead of 3840x2160@120hz and my other 2 Monitors are set to 2560x1440@60hz instead of 144hz ?

In doing the changes from the post, did you set the highest refresh rate between your monitors? Ignore the values displayed in the settings and do a test with glxgears (or alternatives) to monitor the actual FPS in each monitor.

Iā€™d use this to search more infos, there is a troubleshooting section: xrandr - ArchWiki

I tested it all 3 of my Monitors have 120 HZ Refresh Rate that is the Refresh Rate that all 3 of my Monitors share. I Did Read Xrandr and the Multihead wiki page but did find anythin that is usefull for my Problem and nothing that is shown as incorect.
