Video Output

As far as I'm aware Apple has disabled the ability for the iPhone to display video from the dock connector on retail phones.

You can only get video using the iPod/iPhone video cable that plugs into the headphone socket.

 

the iPhone has no video out abilities with legal hardware

 

Yes, you can buy either the composite or component cables from Apple ( Radio Shack stores and I'm sure other iPod sellers, carry them too). They're $50 each, but they include a small USB wall power supply. They plug into the bottom dock connector.

They supposedly work for both the iPhone and Touch. Of course, they're not RGB output to a projector, so if you can't use one of the above types, you'll need a converter. (Many projectors also take composite, but check.)

The downside is, Apple only allows video output for the video and photo apps. So no viewing of the other apps or homepage etc, like Jobs gets to do.

I bought one for my Touch so I could show family vids/photos on our big screen TV. On the upside, people can't see what icons you're clicking, so the show to them is seamless.

If you're trying to show a power point, convert it to individual pictures or a movie.

About what cords work and which iPhone software you need. I'm can't confirm that it will give tv out for anything except movies, so if anyone has some first hand knowledge that would be great.

 

I have that same cable that plugs into the dock and works great to display movies on TV and photos etc. My one beef with it is that it is SO hard to unplug. For a device/cable that is meant to be mobile it is almost impossible to remove the cables without pulling on the cable itself, as the "metallic" connector is so slippery... poor design IMO
