Took pics and video and thought it would be simple PnP to TV. Not quite. First - only your user-generated media can be displayed on your TV. Port a digital copy of a movie to your device - and you can watch the movie from Droid X to TV. Pictures and video you take on the device are also fair game for TV Presentation. Streaming from Blockbuster online or NBC-TV websites...not so much.
Now.. the TV I have is a Panasonic 50" plasma with 3 HDMI outputs (Model # TC-P50G10). On the Droid X > Home > Settings > HDMI > HDMI Format. Change the output from 720P @50HZ to 720P@60. Make sure the cable is firmly plugged in... the correct HDMI input is selected on the TV. Access your media from the Gallery. After you select a video or photo, you will see the special UI for media playback.
