May 2026 Status – HDMI & Miracast Screen Share
Hello Microsoft team,
After moving to Surface 3 with MTR, honestly, the experience hasn’t been as good as what we had with Surface Hub.
Screen sharing is one of the main things we rely on daily, and right now HDMI and Miracast are not working the way we expected. It’s quite a step back for us.
We really hope you can help bring back these functions. If it can’t be done directly in the MTR interface, at least allow it through the Windows side.
This is important for our daily usage, so please don’t ignore this. We’d really appreciate your support on this.

Hi, there has been a useful update since this question was posted. Microsoft’s Teams Rooms release notes state that version 5.6.135.0, released on May 27, 2026, added Miracast support to all-in-one touchboards. I would check the Teams Rooms application version on the Surface Hub 3 first, install all available Teams Rooms and Windows updates through your normal management process, and then perform a full restart. Microsoft describes Miracast as another content-ingest source alongside HDMI, so both should be available once the device is on a supported build and the relevant network requirements are met. If the device is already updated but the option is missing, check whether device policies are restricting wireless projection and review the Teams Rooms logs. The AutoScreenShare setting only affects whether ingested content is shared automatically with remote meeting participants; it does not enable or disable the physical HDMI or Miracast source itself.
