This is an updated version of my previous video on display scaling.
Hopefully this video is more helpful than the last one. I tried to explain everything in a way that everyone can understand.
Please listen to me carefully. I will not respond to comments like "you just broke my 60Hz monitor" etc. I have explained all the ways to troubleshoot and undo changes.

!DO THIS AT YOUR OWN RISK!
