How to Turn on the "TV Out" on an iPhone

If you’re tired of squinting at the screen on your Apple iPhone to watch downloaded movies or video clips, then connecting the device to a television set might be the answer. The iPhone comes with a “TV Out” function so you can view the output from the iPhone on a much larger screen. Enabling “TV Out” on the iPhone is straightforward from the settings menu from the preinstalled iPod application.
