This article reflects information on wired HDMI ingest support on Logitech Rally Bar and Tap (USB), for both Windows and Android scenarios.
It is accurate only up to the date of the article, new changes may have been made since.
1- HDMI ingest on Tap with ZRoA (Zoom Room over Android) and MTRoA (Microsoft Teams Room over Android)— you may see it is already working in public CollabOS, but it is not yet officially supported.
2- HDMI ingest on Rally Bar itself with MTRoA is fully supported starting from CollabOS 1.5.709.
3 HDMI ingest on RoomMate itself is fully supported starting from CollabOS 1.6.303.
4- Audio with HDMI IN is not supported on MTRoA — this is “as designed” on the Microsoft side.
NOTE: When both RB/RBM/RM on-device HDMI IN and Tap HDMI IN are connected, Tap HDMI IN takes priority.
