Let's assume I've created 2 virtual desktops in Windows 10. (#1 and #2)
Is it possible to connect projector with a single virtual desktop only?
Eg. Connect virtual desktop #1 with the projector. Now swap, work along virtual desktop #2 (to look privately for some references at the time of a presentation/projection) and swap back to resume the public projection at desktop #1?

Please suggest any 3rd party tool (if any available) for this use case.
