I have multiple monitors, it can be a pain to line them up using the Windows Control Panel too “Rearrange Your Displays”, sometimes you can’t quite get them to line up, what this means is sometimes your mouse will get stuck going between screens.
A way round this is to use this neat little tool: https://github.com/programmer2514/DPEdit-GUI
It requires Python, but it allows you to line everything up pixel perfect. In theory you can do all this within the registry somehow, but i’ve never figured out exactly where!
