Prevent Parallels Desktop from recognizing external monitor

Question

I use Parallels Desktop (running Windows 10) and have an external monitor, but I dont want Parallels/Windows to detect/extend to said monitor automatically. I like having my Mac on one monitor and Windows on the other, and I can easily accomplish this by going to Display Settings in Windows and, under Multiple Displays, changing from "Extend these displays" to "Show only on 1".

However, I am constantly moving throughout the day and connecting/disconnecting from the external monitor, and, every time I reconnect, Windows automatically detects the external and changes the display settings back to "Extend these displays".

How can I prevent this from happening? Exploring preferences for Parallels didn't come up with anything useful (although I may have overlooked it).

Running Parallels Desktop 12 on Mac OS Sierra 10.12.6.

Answer 1

I have Parallels 10: - when the VM is open, in the Parallels Menu->View I see "Use all displays in Full Screen" perhaps you can use this. - also there is a menu point Devices->External Devices->Configure.
