Microsoft Teams users have been reporting on different online forums [1, 2, 3] about a long-standing bug in the Teams Windows app, which is restricting them from sharing their screens on higher resolution monitors. The discussion forums have been filled with users complaining that screen sharing with a 3440 x 1440 resolution will show a black screen.
Some reports suggested that sharing an individual application on high-resolution screens seemed to work fine, and the problem apparently affected people who tend to switch between applications. However, according to an update posted on the UserVoice forum, a Microsoft representative confirmed that a fix has been deployed in Microsoft Teams version 1.3.00.13565 which was shipped earlier this month.
Many users confirmed on the Microsoft Community forum that screen sharing with a 3440×1440 resolution is now working perfectly. However, if you are still experiencing the black screen problem with wider monitors, you may try lowering your screen resolution to see if that fixes the issue.
Even though the Teams desktop app updates automatically, you can still install the latest version by clicking your profile picture at the top of the app, and then select “Check for updates”. Let us know if the latest update helped you resolve the screen sharing issue in the comments down below.
