How can we use dual screen mode in a Zoom meeting from a Windows Teams MTR?

Hi @Virgil Walker, 

Welcome to Microsoft Q&A forum. 

Thank you for reaching out and sharing your experience when using dual screen in Zoom meeting using Teams Room. I totally understand how confusing it is to see one of the front of room displays go blank when you join a Zoom meeting from a Microsoft Teams Rooms system. 

Based on Microsoft’s documentation, this is expected behavior. When Teams Rooms joins third party meetings using Direct Guest Join (the Zoom join experience on Teams Rooms), the third party provider drives the experience and Teams Rooms supports a maximum of one front of room display for that join method. Microsoft also notes that sending content via the HDMI ingest is not available in this Direct Guest Join scenario.  

If you need a true dual display experience for Zoom (one screen for people and one for content), Microsoft documents that cross platform meetings via SIP join supports two front of room displays and HDMI content sharing, provided your organization has that option configured. 

For more information, please refer to this document: Third-party meetings on Teams Rooms - Microsoft Teams | Microsoft Learn

Dual‑screen behavior on a Windows-based Microsoft Teams Room is controlled and certified only for Microsoft Teams meetings. When using other meeting platforms (such as Zoom) via the MTR, the dual-display experience is not guaranteed and is not configurable in the same way as for native Teams meetings.

For Teams Rooms on Windows, dual display mode is enabled and managed as follows:

1. Dual display requirements
   • A touch console is required for dual display configurations.
   • Only one of the two front-of-room displays can be touch-enabled.
   • Dual display mode without a touch console is not supported or certified.
2. Enabling and managing dual display (Teams-native meetings)
   • In the Pro Management portal: Settings > Device > Dual monitor mode.
   • On the device: Home screen > Settings > Device > Turn on dual display mode.
   • If content appears on the wrong display, use Swap screens:
     • Temporary (current meeting only): during a meeting, open the layout switcher and select Swap screens.
     • Persistent: Home screen > Settings > Device > Swap screen, or via Pro Management portal under Dual monitor mode.
3. Platform limitation
   • The documented and supported dual-display behavior, including layout and swap controls, applies to Microsoft Teams Rooms running Teams meetings.
   • The context does not provide any supported method to extend this dual-display behavior to Zoom meetings launched from the MTR. The symptom described (one display going blank and all content moving to a single screen) is consistent with the fact that dual display mode is defined and certified only for Teams meetings.

Given the available documentation, there is no supported configuration described that would allow Zoom meetings on a Teams Room NUC to use the dual-screen layout in the same way as native Teams meetings, other than the general dual display configuration that already applies at the device level.
