I’m currently experiencing issues with my dual monitor setup. When i connected my second monitor alongside my main monitor, some highly annoying issues appeared. Of course, i can disable the second monitor and all the issues would disappear, but that defeats the purpose of having a second monitor in the first place.
The issues mentioned are as follows:
1 - Minor screen tearing and general choppiness on main monitor
2 - New windows opening on the second monitor instead of the main one, despite the main one being marked as primary.
3 - Blurrier image quality than when used with Windows 10, despite having the same resolution.
Also, i feel that i should mention, i never experienced any of these issues using Windows 10, only the linux OS i have now. I suspect the likely cause for my issues, is the major difference in monitor resolution.
Any help on the matter would be much appreciated. If i somehow discover a solution, i will be sure to update this post.
Here’s da specs:
GPU: AMD Radeon R7 240
Primary monitor: 1920x1080 75hz (HDMI)
Secondary Monitor: 1024x768 60hz (VGA)
OS: Manjaro Linux (Kernal version 5.15.5, KDE Plasma Version 5.24.5)
Right, i keep forgetting i should do that. My bad 
Anyway, here’s the output from that command:
