Start an Aerial screen saver
Your Apple TV displays a screen saver after it's idle for a certain number of minutes. You can start the screen saver at anytime. Just go to the top-left corner of the Home screen on your Apple TV and press the Menu button on your Apple TV Remote.
To change the number of minutes before a screen saver starts, go to Settings > General > Screen Saver and select Start After.
Aerial screen savers aren't available on Apple TV (2nd and 3rd generation).
