I am wondering that how to connect my nexus 7 to Google TV, so I can play media wirelessly with the Logitech revue. However, the N7 tablet doesn't have HDMI port out. It's no way to hook it up to a TV at all.
If you want to wirelessly stream the Android Media from nexus 7 to an HDTV, go to purchase "AirSync by doubleTwist" from Google Play and use it for that. With the app, you can play the transformers movie on N7 to HDTV or Apple TV over Wi-Fi. It also supports streaming video, music and photo to Xbox, PlayStation 3 and Sonos devices.
