When attempting to share content within an MS Teams conference via HDMI, a green screen displays for the far end when the near end is the presenter (only where it is a combination of a RealPresence Visual Pro and Trio 8800).
Poly Firmware version 6.2.2.1-600016 (Visual Pro)
Poly Firmware version 7.1.0.8045 (Trio 8800)
I have been advised that this could potentially be caused by a content protection issue, but in the scenarios tested an Apple Computer is not being used and I cannot see any reference on the Web UI for either the Visual Pro or Trio 8800 to disable HDCP Content Sources.
I have provided an attachment of what displays for the far end (please ignore the black blocks either side of the green screen as I have blocked out the participants camera).
