Issue with Multiple Displays

Trying to add a second monitor to my setup. Currently have a monitor using a display port cable. I tried to add a second monitor to the video card via the DVI cable and windows 10 sees it okay and identifies it just right.
However unless I am actually dragging something my mouse will not go between the monitors. If I grab a window and drag it then it will go over and I can move back and forth for a short time but then it stops and no longer will go across.
One monitor is at an extremely high resolution with the DPI set at 150% and the other is a 19" at 1920x1080 at 100% DPI.

Everything displays fine when it gets there but it is just the mouse issue when not dragging anything. No way to get to the other monitor.

Anyone had anything similar? Have tried google but found nothing yet.

Have you checked in display settings they are oriented correctly. Hit identify, and make sure they are displayed as physically located



Also make sure you are using extend these displays

Yep all been done. Monitors are showing they are where they are supposed to and they are on extend.

As I said it works as it should if I am dragging something with the mouse but after dropping it will only work for about a minute and then the mouse will no longer go to the second monitor.

Have you tried another mouse?

Because it stops working, so it could be the mouse

I would try another mouse if available, or at least another install of the mouse software
