Hello all, as per the title description it was allw orking fine until latest days. When I share my full desktop in teams, other people sees a black screen, but sharing a single application works.

I've tried with the web app and it works fine, it's the local installation that is not working.

I've already tried to reinstall Teams and cleared all the cache but issue persist.

Anyone can help me out? it's driving me nuts

Thanks

Carlo

    For me, it's black when I have the primary monitor (laptop) mirrored to the larger monitor.  When I split them, so the displays are not mirrored, it is useable on my laptop monitor, but unusable (black) on the larger monitor.

    yes, because it's the widescreen resolution that does Teams does not digest...

    was working than MS broke something with an update. Tehy say fix coming soon, but last time I saw This is coming soon" was on the option to add more than 4 people in the webcam view... and it was from 2016 :D

    Hope they will REALLY fix it "soon"....

    Same here. Widescreen Dell U3419.

    Actually on Skype for Business I have the very same issue. both running on my Desktop computer and on a Lenovo Laptop, both connected to the Dell. On the Lenovo I can move all windows to the Laptop's screen which i want to present.

    But thanks for the hint with reducing the screen resolution. not great, but better than always sharing a new window when switching between apps that i want to show.

    hope they fix that soon too.
