I saw in the release notes that HDMI video ingest from a device in the room is supposed to work now in with Teams provider if I'm running 3.9.0. I updated my X50 to 3.9.1, however, and Teams still says that it doesn't see an HDMI input if I try to share content.
The HDMI source I'm using (my laptop) works just fine if I swipe left and go into Device mode.
Any tips on how to get Teams to recognize the HDMI video?
