Apple VGA adapter
If you're interested in using the iPhone 4 for slideshows, video output, or presentations, Apple offers a $30 VGA adapter that can connect to a projector, computer monitor, or many digital televisions. It has a maximum 1,024x768-pixel resolution output, so keep your HD expectations in check.
Composite and component video output cables are also available for purchase. All of the adapters are capable of playing video content (movies, TV shows, video podcasts, YouTube) to your television, provided the connections are compatible.
