For IPad users that want to mirror they’re devices onto the big screen, it is possible!
Projectors with HDMI inputs makes it simple to connect the Apple TV to be able to mirror your IPad onto the big screen. But now with OSX Mavericks, instead of mirroring your laptop you can now use the Apple TV Projector Screen as an extended monitor.
You can see how to set up a Apple TV with a projector in the video below.
Once connected simply use your IPad or MBP and Airplay like normal.
