Question: Why would only the audio work? I have it plugged in correctly
Document: Didn't work at all for my iPhone 4s. It's hard to figure out how to plug it in correctly. I wouldn't buy it again.
Plugged it in to the standard def video and stereo audio in on a 32" Sony LCD TV and it worked great. Picture quality from Netflix was very good considering the format. It does display the video slightly smaller than the TV screen size but totally acceptable. The video does not mirror on the phone itself, on the phone you will just see the Netflix logo. Only shows video, not apps, but that's what I wanted.
All I wanted to do was use my iPhone 4 to stream Netflix into the minivan's entertainment system. This cable fit the intended purpose as expected, so I recommend it. I'm sure the kids will now have a much better time on long road trip this summer.First I set the van's audio and video inputs. Then I plugged this in and ran the Netflix App, after that I hit play and everything was good to go. Very easy.There are only three minor situations to note:1.
While it did take some tinkering to get it working correctly (aided by jailbroken apps too), it did display the photos, springboard, and apps correctly. The only problem is that if you touch the cable or move it ever so slightly, the picture would distort -- easily proving that the quality is substandard.I can understand the picture distortion if a child moves/tinkers with the dock connector while it's connected, but I'm only talking about cable itself.
Main iphone plug is very loose at the bottom, you have to hold it at certain angles in order for the cable to work correctly.
Plugged directly into my iPod 2nd gen and then into my Vizio TV AV2 inputs. Pulled up YouTube video on iPod, selected AV2 from TV menu, hit play and tah-dah, both audio and video worked perfectly! Only suggestion is to use caution removing cable from the packaging--easy to imagine it being damaged by anyone trying to tug it out instead of carefully popping it out of molded soft plastic casing.
The AV cabling is well made but doesnt fit as snug onto the Iphone 4 as I would have liked. While taking out to my car, it came unhooked twice.The Jacks are well Identified by color  and easily connect to the outlets on my DVD Play. Once plugged in the Iphone indicates that it its going it TV mode. Great... Sadly no picture. Ok  Test 2  Plugged into my HD Sony TV. The system found it right away and I was able to get a picture of sorts.
Another slight annoyance is lack of labeling for audio Left vs Right. Overall it seems like a decent deal if you want to save a little and have newer Apple devices. I would have given it a 4 or 4.5 star review except for the issue I'm having with the 3GS. I'm not ruling out an issue with my phone though, will continue to dig around and see if I can resolve it.
I bought this cable for streaming netflix on my IPad2 to my TV because I dont have cable. The cable works fine but it says it doubles as a charger which it doesnt. It probably works if plugged into a computer or laptop but it does not work when plugged into my TV :-(
I bought this expecting a fight with the tv and iPad because this stuff never works quite like advertised. I plugged it into my iPad, plugged the other end into the tv, pulled up Netflix and we were ready to go. It took some fiddling (technical term) with the tv to get the video to work (had to unplug the cable video cord), but that only took a couple minutes.
Answer: It will depend on the application you are using.  Netflix and Hulu should give you audio and video, but I know Hbo go does not support video out.  What app are you using?
