Scaling on Monitors Messed Up

LG123 · 27 Jul 2022

Hi,
First post here. I just got a second monitor and it is really messing things up. One is a 27" QHD (2560x1440) and the other is a 19" 1280x1024. It seems that Windows settings for dual monitor set-ups are based on pixel density alone because when moving from one to another, the cursor changes size, mouse sensitivity changes and the cursor jumps upwards from one to the other. Are there any known fixes for this? I can't believe that a massive corporation like Microsoft hasn't found some kind of fix for this basic issue.
Thanks in advance.

Windows version 21H1

In Settings > System > Display, have you tried playing with the Advanced Scaling Settings?
Turn Windows Automatic on and off to test, try some custom scales for each monitor.

Also note that if you are running older programs that some of these do not understand very high resolutions and are not capable of scaling correctly beyond 1080p. You would notice this if Windows and more modern progs scale correctly, but others don't.
