A few months back (before it launched), we found out that the Droid X would have limited HDMI functionality - mainly, it would only work in gallery mode. Today, we stumbled upon a new app on AppBrain called Real HDMI that seems to remove that restriction. Check out the item description:
Warning: This only works for the Droid X.
Finally you can enable and disable the HDMI port on your Droid X. Use your favorite video players, applications and emulators on your big screen TV or Stereo.
- HDMI Video/Audio Out
- Car/Media Dock Modes

User reviews for the app are overwhelmingly positive - it has about 4.8 stars (out of 5), and is in the 100-500 downloads range.
