Hi. I'm David, and I'm happy to help you.
Besides lining up the monitor boxes to match your desk, a few details can still mess up cursor movement:
- If one screen sits above the other (like a laptop below a desktop monitor), drag the boxes top-and-bottom in Display settings instead of side-by-side.
- If your screens are different sizes, go to "Settings (Windows + I) > System > Display > Multiple displays" and check "Ease cursor movement between displays". This stops the mouse from catching on the uneven corners.
Feel free to ask any questions you may have.
