How does PP920 pico projector work with iPhone 4?

1. You need to have an Apple Composite AV cable from Apple (from the third party is not recommended)

2. Connect Apple Composite AV cable with iPhone.

3. Connect the yellow end of Apple Composite AV cable with and attached RCA connector/ video cable. And then, connect to the PP920 pico projector.

4. 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 (without sound output).
