4. Due to iPhone chipset protection, almost all projectors in the market connecting with iPhone can project ONLY images and video, not able to project everything displayed on iPhone. 


Normally, iPhone can video-out to the projector only in the following three situations:
-- playing image slideshow
-- playing YouTube
-- playing iTune movies


5. For a jailbroken iPhone with installing TVout or screenSplitr from Cydia, the projector can display what shown on iPhone.
