HDMI Share is the application that can be used to display web cams, connected laptops, TVs and wireless display devices.  The FAQ gives an overview of the HDMI Share application and how to use it.

What can I do with HDMI Share?

HDMI Share can display most any kind of USB Video Class device (UVC).  This includes: web cams and HDMI capture cards (for TVs, laptops, wireless display devices).  Although we have not tested all UVC cameras, most should work.  For recommended HDMI capture cards, please see: Supported HDMI Capture Devices for more information.

With HDMI Capture devices, HDMI Share can either start from an action tile, or automatically start when video is being displayed (e.g. when a laptop is plugged in).

With UVC Cameras (web cams), HDMI Share can start with an Action tile.

HDMI Share can display many feeds on one screen with Picture in Picture or Tabbed display.  It can also have a prompt for a user to plug in their own device.
