I seem to have a strange issue.
I have a screen that i want to share between the Surface Pro 4 and my Desktop. The screen is plugged into the UD 3900 with a DVI cable and then i plugged the UD 3900 into a USB switch that goes to my surface and my desktop. My keyboard and mouse are also plugged into the UD3900.
When i start up the desktop (which has another separate screen) it goes into dual screen mode and everything works fine. When i then click the USB switch, the surface pro 4 recognizes the second screen and mouse/keyboard and everything is fine.
Then when i switch back, the controls and mouse moves over, but the screen remains stuck on the surface, or at least the visual gets stuck on the screen because the surface wont allow access to it anymore. The mouse and keyboard moves over to the desktop pc but not the screen.
What could be causing this issue?
