You cannot connect the cameras to your TV to play a 3D file. You will not have a 3D file until you convert the two 2D files recorded by each HD HERO camera into a single GoPro 3D media file. So, you will not be able to playback in 3D directly off the camera. You will need to use GoPro CineForm Studio in order to create a 3D file from the files you recorded using the 3D HERO System. Once you have a converted file on your computer, you can playback on a TV from your computer, or export the file for playback using a different device.
