Apple TV

The Apple TV uses the Airplay system to stream audio and video from a compatible Apple computer or mobile device to a television, projector or other external display.

DVD playback and chequerboard pattern on-screen

 * Apple Macs come with a DVD player application, found in the Applications folder. This application cannot be used to play DVDs on an Apple TV using Airplay. If DVD Player is used to play a DVD on an Apple TV, a chequerboard pattern will be displayed on the screen. DVD Player works normally when the Mac is connected to an external display via a cable. To watch DVDs via an Apple TV use VLC media player instead.

Apple TV displays picture but no sound - MacBook users

 * Ensure the volume control on the Mac is set to a reasonable level (F11/F12) and hasn't been muted (F10).
 * If using VLC check you have the correct sound output selected. To do this go to VLC > Audio > Audio Device and select your preferred output.
 * Check the Sound settings in System Preferences. In the Output section there will be a list of available devices, make sure the correct Apple TV is selected.
 * In rare situations you may find you try the above step but the selection keeps returning to the default choice of Internal Speakers. In this case go to the Airport icon on the menu bar and select Turn Wi-Fi Off, wait a few seconds until the icon turns to a grey outline and then turn it back on again. If the problem still persists restart the computer.

Lecture Theatre

 * The Lecture Theatre offers both Apple TV and a direct wired connection. There is a small switch box mounted on the rear of the projector, button "A" selects the Apple TV as a source and button "B" selects the direct cable input.


 * The Lecture Theatre's Apple TV is identified on the network as PED13.
