Just got a new Apple TV for use with my new-ish Panasonic 65" plasma display. I want to use the ATV primarily as an easy way to view photos (via AirPlay) stored on my iPad 3, iPhone 5, iPhone 4, and MBP. AirPlay works just great with all of those devices, but the photos themselves don't look as sharp as I was expecting. Of course, they look super sharp on the iPad and iPhone, but look just a bit 'soft' on the Panasonic. Is this an unreal expectation, given that the photos are being blown up so much, or is it the fault of the AirPlay process?
