Apple recently unveiled the iPad 2. Among other enhancements, Apple announced that the iPad 2 will be able to perform HD video mirroring through Apple’s new HDMI adapter.

The adapter plugs into the device’s 30-pin connector and automatically mirrors the iPad 2’s screen to an external source in 1080p HD. Setup requires no configuration and works instantly when connected.

What Apple didn’t say in yesterday’s event was that their new Digital AV Adapter will also work on the iPhone 4, 4th gen iPod Touch, and original iPad.

Apple’s HDMI adapter allows you to pipe any content from your iDevice to an external screen. One side plugs into the iDevice’s 30-pin connector, and the other connects to an HDMI cable for your TV.

There’s an extra plug in the adapter for an Apple USB cable. You can charge/sync your device while you are mirroring on an external display. (Nice touch, Apple.)

Although Apple has marketed this new adapter for the iPad 2, the device’s description in the Apple store clearly states that it is also compatible with other iDevices.

“Watch slideshows and movies on the big screen in up to 720p by connecting your iPad, iPhone 4, or iPod touch (4th generation) to an HDTV or HDMI-compatible display.”

The iPhone 4, iPod Touch, and original iPad can only output video at the max resolution of 720p. The iPad 2 allows for full, 1080p HD video mirroring.

Besides the resolution difference from the iPad 2, Apple’s new adapter will work perfectly on the iPhone 4. Apple’s Digital AV Adapter will be available for $39 on the same date as the iPad 2 launch (March 11th).

Previously, iPhone users had to jailbreak and install mods like TVOut for displaying the iPhone’s screen on an external display. And even then, the output was not in HD.

Will you be buying Apple’s new HDMI adapter? There are so many possibilities with the ability to mirror your iDevice’s screen on an external display. We can’t wait to get our hands on this adapter.
