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

    Hello,

    i have the same issue. I use an Acer Predator with the resolution 3440 x 1440 with a Dell Latitude.

    Did some testing my self and dont know if it helps anyone, but here are some results:

    Intel HAXM + secondary widescreen => black screen

    Intel HAXM + main screen => will be shared

    Hyper-V + Hypervisor + secondary widescreen  => shared with delay

    Hyper-V + Hypervisor + main screen  => shared without problems

    Browser + secondary widescreen => shared without problems

    Browser + main screen => shared without problems

    Dont know if its realy a problem with HAXM but in my case i need to deactivate it and use Hyper-V to share a widescreen.

    Same issue with a fresh reboot of my desktop machine and a fresh install of Teams.  

    3440x1440 does not work but if I lower the resolution to 2560x1440 it will work.  Note this is my Microsoft Supplied work Monitor.  Which is pretty standard issue for our team so assume most of our group has this issue.
