[Windows Central Question]

Hi, I run the sound and vision at my church.

We use one PC and one MAC which feed into an A/B switch box to route the video signal to a data projector.

Until I upgraded the PC to Windows 10, the change from one machine to the other was seemless. Switching video sources back and forward did not require any other intervention.

Since the Windows 10 upgrade, the PC does not automatically recognise the return of the data projector. I need to stop Powerpoint, go into the display options, detect the second "monitor", and restart Powerpoint to resume the data projector display. This results in my screen background displaying, and everyone seeing my workings.

Does anyone know what is happening here, and how do I fix it?

Thanks, Peter

Did you try directly, without the A/B switch? I am using the same monitor on my PC and MAC and switch from one to another without an issue.

Granted I manually take the cable from one and plug it into another. Also I haven't tried it while using PowerPoint, as I mostly interchange the Monitors and PC/MAC during development.
