I received my microHDMI cable today and just tested the feature on my TV at home. Works on: - YouTube app - Built-in video player app "Videos" - Built-in gallery app "Gallery" - Slideshows of pictures in gallery app. Does not work in: - Camera app - Video recorder app - Qik video app - SprintTV - Home screens or other apps (does not send video out of navigating the phone) Quality: If the original video looks great, so will the output from the Evo. Video taken with the Evo in 720p looks significantly compressed and overly "sharpened", but still the best I've seen on a cell phone. YouTube HQ videos looked good as well, but again, depends on the quality of the original. Not quite as good as a ripped dvd but hardly noticeable. Sound always came through well with no discernible loss of quality. What blew me away, though, was viewing a slideshow of pictures I took with the Evo. They looked fabulous on my HDTV! Colors were rich and detail was stunning. I was actually surprised the video did not show up on the TV when opening the camera app. Would be nice to be able to view what your camera is pointing at on a big screen. Also, when it actually is broadcasting through HDMI, the Evo's screen is black except for some navigation buttons. Would be nice to have the option to show both. Overall, I'm happy with the performance. It's a great feature that can come in handy on vacations, watching movies, browsing YouTube, etc. Worth the under $20 price for a cable. -------- Sent from my HTC Evo 'cause that's how I roll.
