Dual Play connects two devices using a wired (Slimport-HDMI) cable or a wireless connection (Miracast) allowing you to view content on a different screen. The connectable device can be a TV or a monitor supported by an HDMI cable or Miracast. Viewable content can come from the Gallery app, however not all videos are supported by Dual Play.
To start Dual Play, tap the Home Key (in the Touch Keys bar) once when the two devices are connected and their displays are a different status (i.e., the monitor is playing a video and your phone’s video app is displaying an empty screen.
Dual Play operates at 1280x720 or higher display resolution.
