Poor substitute for the Apple AV adapter
591930
This adapter relies on a clever hack, using the iPhone's wifi to broadcast a video signal which is then converted to HDMI. (The Lightning port is just for power.) But setup is a clunky process, it doesn't work for iPads, and the video is noticeably degraded in quality. It's cheaper than the official Apple Lightning Digital AV adapter, but it's also far more limited.

I used this to connect a Mac Mini to my HDTV. The picture was worse than my DVI to VGA connection.

Sound quality is not great and av jack for speakers are even worse.

Tried to use it with a Moshi Minidisplay port to HDMI adapter, in order to connect my Macbook to my Sony TV, with sound.  It did not work at all, and at first I thought it was the adapter, but the adapter worked with a different cable.  So yeah, it just didn't do it for me.

Doesn't work well with 2013 MBAir - image goes offscreen and Overscan slider is not available in Display Preferences. Cable does not transport display resolution to MBAir.  Video image is noticeably distorted and off screen.  Connection is unstable and sometimes freezes the laptop.  Other MiniDisplay Port adaptors do not have these problems and are much better.

Its the wrong adapter. It plugs into my mac but the female end is not HMDI compatible to my television. I need to return it for the correct product. Please contact me as soon as possible.

I made it work after an hour at the end of the day I m going to just connect it to my Apple TV through a cable, I guess AirPlay is not that great :/

The adapter came apart on EACH END as I plugged it in.  All the wires were exposed, I had to glue the plastic pieces back together.  I have to wiggle the plug around in the plug at the back of my iMac for it to work.  Even then, it only works sometimes.  I guess that is why Apple wants $30 for theirs, and this was 1/10th the price.  I wouldn't recommend this... spend a little bit more and get something that works.

I was using this to hook up my Apple TV to my Smart Board in my classroom, but when I connected it, no picture or video showed up on the screen. Luckily it was cheap, otherwise I would've been even more frustrated.

This connection adapter was not compatible with apple products. Took it to my once in a lifetime trip to Africa and was not able to download my photos.

Although this microphone has gotten many good reviews, I do not recommend it. I purchased this for a journalism class and was very disappointed because my professor recommended it for us, but both Amazon.com and the actual Olympus site fail to state that an adaptor is required to use this with a Mac product. Considering every student in my class has a Mac product, I'm not sure why the professor didn't mention this...but Amazon needs to be more clear on what is required for this product. It is not a standalone product at all.

I agree with the above reviewer (Aaron) for the most part, with the exception of his statement that the product does what the description says. It does what the Amazon description says, but the Apple website claims that the product allows you to watch videos through your TV if you have composite or component AV cables. It does not. If you want to use it to watch videos you have to have a set of apple's AV cables, which work fine on their own. All that can be said about this dock as far as video is concerned is that it does not disallow video out. A lousy waste of money.

Attempted to connect Apple TV to plasma tv. Adapter works but tv doesn't support HDCP so Netflix does not it work.

Does not work for my Apple TV to Sony Plasma TV.  Screen does not sync up, even if I manually try to set it to 720p.

This cord was advertised to be compatible with the iPhone 4 and lower, well when I received it in the mail I hooked it up and all that played was AUDIO. And the BOX said only compatible with iPhone 3 and lower. I was very disappointed because I had searched AV cords compatible with iPhone 4 SPECIFICALLY because that is what I have and I have tried numerous times to have the correct one sent to me but have had no response

I tried the adapter but it didn't work in my 2.0 USB. All I got was a very slow response and a whole lot of buffering. I returned it. I'll probably have to go the route of getting an HDMI card for my PC.

Seems to work fine with apple TV however not blu-ray players. Each player (we tried 3 different brands) seems to work when directly connected to the TV but not when connected to the TV through the sound bar. I could not recommend this sound bar. Also of note is how difficult it is to get support from Amazon on something they sell. I still have not found a solution.
