Black screen when sharing your screen in Microsoft Teams?
Screen sharing with the latest Microsoft Teams version (built) show a black screen at a resolution of 3440 x 1440 when you share your screen.
An annoying but practical solution is to lower your resolution for an important meeting to: 2560×1440 or lower. You can do this via this blog.
It doesn't look like UserVoice will help, but it's worth a try.
