Sharing the screen as a whole actually creates a mediocre user experience on the other side(s), to say the least (even if they could zoom locally...). I therefore only ever share single Windows (not full screen; e.g. from browsers) or else PowerPoint natively when working on this screen. This works well - however, when changing the content to be shared, the sharing must first be stopped in order to share the new content afterwards (there is no direct change - except from one browser tab to the next).

I don't use it like that and have never tested it, but theoretically you could display 2 inputs on the left/right. This way you could attach two "virtual" screens to your device if the connections are available, e.g. 1 HDMI and 1 DP, or 1 USB-C and 1 HDMI. Then you can split the left or right half via teams, because it is then 2 screens for your PC.

Works perfectly.
