at first it didn't work, only audio was passing through to my HDTV monitor, but after I did a little research on the Internet (aka google'd it) I realized that my iPhone 4 is not capable of streaming the HDMI video - it's a known limitation of that version of the Apple phone. It does work great with my iPad 2. I am a happy customer. This item is 1/2 the price of the Apple HDMI adapter cable plus the Patuoxun version allows charging of the device simultaneously. No more worries about whether the iPad will have enough battery juice left to make it through the entire movie.
Output:
worked great for me
