No, Miracast itself does not support broadcasting. To project your laptop screen to multiple ViewBoards simultaneously, please use the AirSync "Group" feature or ViewSonic Manager.


Solutions:

  1. AirSync Grouping:

    • Launch AirSync on the primary ViewBoard.

    • Use the "Group Connect" mode to include other ViewBoards on the same local network.

    • Content projected to the primary display will be broadcast to all grouped screens.

  2. ViewSonic Manager:

    • Administrators can broadcast multimedia content or urgent messages to multiple ViewBoards remotely via the management portal.


Note:

  • Miracast is a peer-to-peer (1-to-1) protocol. For large-scale broadcasting with high stability, software-based solutions like AirSync Group or hardware HDMI splitters are recommended.
