How can I output video from my HTC Thunderbolt to a TV? Could somebody please detail for me a system using which one can output video to a TV from an HTC Thunderbolt? It has no HDMI port so I'll (almost) certainly need an adapter, I know. I don't really need HD quality but at least 720p would be nice.
The Thunderbolt has DLNA, so if your TV supports DLNA you can use that.  On my Samsung phone, you use the AllShare app for DLNA, but I think the Thunderbolt has another app built in.  Page 275 of the User Manual describes how to use DLNA.  This droidforums thread has a discussion of ways to use DLNA without a compliant TV, I'm not sure how well other ways will work.

There's also a "multimedia dock" that is supposed to be released shortly, it's "out of stock" until then.  That should provide a cable-based way of video output.
