Lowering monitor refresh rate

I am trying to create a custom refresh rate for my monitor (98Hz) as my monitor has a bug where if it runs at 100Hz it will skip frames.

I have tried following the arch linux xrandr guide

However after following the steps and running xrandr --output DisplayPort-1 --mode 3440x1440_98.00
i am left with a blank screen and i have to change it back to 100.0Hz on my other display.

Any idea what i am doing wrong? Thanks :slight_smile:

Your monitor probably can’t handle that refresh rate at that resolution properly. What it the output of xrandr?
