Can't detect 120hz on monitor

I have installed Garuda today coming from Manjaro KDE, everything looks fine except that display configuration issue & unexpected Dolphin crash.
I am working with Acer Nitro Monitor 144HZ connected to the laptop using HDMI.
The issue is garuda unable to detect the 120HZ only showing the 60hz and the most strange thing is that it's showing the 120hz option on my screen laptop which is only 60HZ and when I choose 120hz the whole application crash.

It maybe a bug, but...
first you have to re-arrange monitors. Now they seem as Cloned, which means you can't have different settings for each one.
Also, it depends if you have dual GPU and the output is from the 2ndary one.
Check with xrandr.
The cable you use has to be capable of 144Hz. Have you been using the same cable with other OS and had proper output?


Yes i was using 120hz on manjaro KDE same monitor same configuration as listed above,
but i think in manjaro i was using 120hz with 2560x1440 resolution which is not available here.
Looks like the 120Hz option only available on 1920x1080 resolution
can i set it to use 120hz on 2560x1440 resolution?
and why its showing 120hz option for laptop screen and its not listed in xrandr result

  • Your system Xorg server can see only 60hz for eDP-1 and can not use this monitor at 120Hz.
  • Your system Xorg server can see 120hz for HDMI-1 and uses this monitor at 120Hz, as marked by the asterisc. It can also use it at 60Hz.
  • If you want to use both monitors cloned, you can only do this at 60Hz.
  • If you want to use the external (HDMI) monitor at 120Hz, you can only do this with a different screen area (not the same as eDP-1 area).

I suggest:

  1. Set external HDMI monitor to 60Hz
  2. Enable eDP-1 and set as Primary
  3. Drag monitors in Monitor Settings GUI, so they are at different areas (side by side, top and bottom, etc)
  4. Set external HDMI monitor to 120Hz
  5. Apply Settings

Having a similar issue. I am a long time Open Suse user and recently started using Garuda primarily as a gaming OS. I have a Valve Index and the VR HMD works in 120hz with no issue but my tv only refreshes at 60 and that appears to be the only available option detected. This tv works at 1440p_120hz in windows perfectly.
I will be grateful for any assistance anyone has.
