Through amdgpu_top several modes are available, with [email protected] being the preferred

however after turning on/off the display, it reverts to 144hz

how can I make 160hz the default ? kde settings shows “A new output has been added. Settings have been reloaded” when this happens; and the previous 160hz is saved “for any display arrangement”

    Have you double checked that the monitor itself has native refresh rate of 160, not 144? Otherwise I’m stumped.

      Yeah, it’s advertised as 160hz and even amdgpu_top (which uses xrandr or something like it) says 159.96hz is the first preferred mode, the second being 100hz

      I had this problem before with a Nvidia card which reset to 144hz after an update and I could never enable it again. However it’s a mystery as to why it boots up at 160hz in systemd-boot console, and goes back to 144hz when entering KDE or turning the display off

        Hmm…maybe test what it does when you boot into live on USB or a different distro altogether, just to isolate whether it’s specific to this distro/configuration or something to do with your hardware?
