I don't know much about Apple products but I wonder if you have to use it with the Apple TV unit?
Says right here on their Site
"Play content from your iPhone, iPad, or iPod touch on your HDTV.2 Watch movies, play music, show off your videos and photos — even show what's on your screen to enjoy games, web pages, and more.3"
Using their device of course.
