Use the Digital AV Adapter from Apple to mirror content from your compatible Apple devices onto an HDTV or other HDMI-enabled display. The adapter supports up to 1080p HD resolution, and sends digital audio to screens that support it. Simply connect the 30-pin connector to your device, and the HDMI connector to your display. A second 30-pin connector is built into the adapter, which allows you to charge and sync your device while it’s connected to the display.
