Although the Apple Digital AV Adapter came out during the iPad 2 announcement, it will also work with the 4th generation iPod touch, iPhone 4 and first generation iPad. The Digital AV adapter plugs into your device via the 30-pin dock connector. An added bonus is that there is a second 30-pin connector on this adapter which allows you to charge, and even sync, your compatible iOS device while viewing media on the big screen.
When paired with your iPod touch (4th generation), iPhone 4, first gen. iPad or iPad 2, this nifty little adapter allows you to flaunt your media on your HDTV or HDMI-compatible screen. You can show off your vacation photos with a nice slideshow, or you can sit back and enjoy your newest iTunes movie rental.
What really makes the adapter special is that when it’s paired up with iPad 2 it will mirror whatever you’re doing on the device (using an app, reading a book, surfing the web, etc) on your HDTV or HDMI compatible display. The iPad 2 supports up to 1080p and the first gen. iPad, iPhone 4 and 4th generation iPod touch support up to 720p. The Digital AV Adapter will also carry over digital audio to your HDTV or HDMI compatible display if supported.
