Video: Apple iPhone 2.2 SDK has TV out feature
While looking at the Apple iPhone 2.2 SDK, Ars Technica discovered MPTVOutWindows which apparently does exactly what it sounds like and that is it sends video out via the Apple iPhone Dock Connector port to an external screen.
This theoretically means it allows applications intended for screens bigger than the Apple iPhone’s 3.5 inch LCD and was primarily meant for movies. However tests reveal that touch input is disabled in this mode and so prevents the iPhone from being used as a regular controller for presentations or games.
Developers are already aware of the limitations and have already written basic code and are planning on exploring the MPTVOutWindows further in future. But we have a video example of this below.
