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
