My usecase is videoconferencing and screensharing:
I have one big 4k monitor.
With MS Teams, unfortunately, you can either share ONE window or an ENTIRE screen. In sessions where I need to share several windows, but not the entire screen (as there might be other apps like my calendar or outlook, which the audience should not see), this is very uncomfortable/impossible with MS Teams.
Thus, I’d like to have a virtual monitor device (spacedesk?) where I can place all the windows I want to share – and I want to control it via my mainscreen within a window. Then, in Teams, i could choose either the virtual screen or the viewer as source for the sharing.
