Use the Apple Digital AV Adapter to mirror whatever's on your iPad or iPhone 4S screen - apps, presentations, websites, and more - on your HDTV or HDMI-compatible display in up to 1080p HD. Watch slideshows and movies on the big screen in up to 720p by connecting your iPad, iPhone 4, or iPod touch to an HDTV or HDMI-compatible display. The Apple Digital AV Adapter routes digital audio to screens that support it. Connect the Apple Digital AV Adapter to your iPad, iPhone 4, iPhone 4S, or iPod touch via the 30-pin dock connector and to your HDMI-compatible display using an HDMI cable. A second 30-pin connector built into the AV adapter lets you charge and sync your device while it's connected to your HDMI-compatible display.
