Manually set monitor refresh rate with xrandr

My recent distro hopping has found some distros don’t let you change your monitor’s refresh rate via the GUI. After a while I found this post which explains the syntax for xrandr to force the refresh rate of 100hz (adjust to your liking)

xrandr --output DP-0 --mode 3440x1440 --rate 100

Create an auto start item with this line of code in it to get this to happen automatically on startup.
