Product Description

Product Description

Bring a true digital experience to your home theater with our fully digital Mini DisplayPort adapter that supports 1080p video and digital audio for Apple MacBook, MacBook Pro, Mac Mini, iMac. With audio limitation from Mini Displayport we've combined Apple Mini Jack digital audio output with Mini DisplayPort digital video output into a single HDMI output solution to bring a true audio video experience with full HD 1080p video and full digital audio 5.1 support. Powered by USB so no external power source is needed.

From the Manufacturer

Bring a true digital experience to your home theater with our fully digital Mini DisplayPort adapter. The Kanex iAdapt 51 supports 1080p video and digital audio for Apple MacBook, MacBook Pro, Mac Mini, iMac.

Combine high definition video and digital surround sound to create the ultimate home theater experience.

Automatic EDID and HDCP compliant

This cable has an auto�EDID feature built-in that adapts to maximum resolution depending on users display. If a user has a 720p HDTV, it will read the EDID and adjust Mini DisplayPort output automatically and vice versa for 1080i/1080p displays.

5.1 Surround Sound Audio

The iAdapt 51 provides digital surround sound for well-equipped Mac models released as early as 2008. Listen to your movies and music in surround sound. Supports uncompressed 5.1-channel audio such as LPCM and compressed 5.1 channel audio such as DTS Digital or Dolby Digital.

Mini DisplayPort meets HDMI

Connect your Mac with Mini DisplayPort to any HDMI HDTV or projector. Now you can break free from your single display and view your content on a high definition display.

USB-powered

Don't bother with cumbersome power supplies that take up space. The iAdapt 51 includes a USB connector for power. It's even equipped with a red LED light to let you know it's on and working. Plug and play is easy!

My computer would sit there flashing a blue screen while it tried to detect the output device.

This is the only option to connect my late 2008 Macbook Pro to my AV receiver with one cable for video and audio, so one star for that feature.

The second time after a return and wait period, it just barely worked after multiple attempts then failed after a couple of days.

This product is about 90% of the way there. But it's not ready for the living room.

Like many other reviews, I can definitely claim that this device did not work properly out of the package. It was definitely easy to set up. No manual was required. However, the resampled audio is not correct. There is a 1/8th second clipping noise. You can determine if your Kanex is broken, too, by playing a pure sine wave audio clip. If you hear a pure tone, then your Kanex is probably fine. But if you hear a pulse, you have a broken one like mine and others. It does this for both digital and analog passthrough.

I left it plugged into my mac mini overnight. The next morning I decided to google around for clues, but by then the chip was overheating and the HDMI video synchronization was lost. It would reclaim the sync every few seconds, in a periodic failure.

In a nutshell, I surmise they rushed this product out, when another month of QA testing would have yielded a properly working chip. Oh well, it was a really good attempt! Have to rate it as a complete dud though. I'm not even an audiophile and it was too lousy for me!

Posted from mac forums:

It no longer stays connected to my computer. It loses the signal and stops working after a few minutes no matter if I am booting the computer or waking it from sleep.

I'm pretty computer savvy and after working with all of the settings on the TV and computer, nothing worked. I have determined that it is fact the Kanex connection. I'm pretty sure the product has degraded to the point of not working at all now.

I would suggest not buying this product.

After attempting to working with Kanex, I found out that none of their contact forms or emails work so you can forget any support help too.

Update:
7-13-10
I got an email from Kanex saying they will replace it for a new one. I am pretty sure even a new version is going to fail so

I ordered the simple MDP to HDMI adapter and that would not work with my TV at all. I spent even more time with the Kanex adapter and although it connects with perfectly fine audio, the video connection is not right. I get pixellation as if it was connecting at 320p. I ordered another adapter that will adapt dual link DVI-D to HDMI. I think this is okay but after spending $100 on adapters and I really wanted to avoid using a toslink cable into my receiver since I only have one port.

I will post one more update so all of you trying to work with the same issues will know what you need to do. I hope the DVI-D to HDMI does the trick so I can put this issue to rest.

Update:

I bought a $3 dvi-d to hdmi connector and it works like a charm. The picture is perfect, never goes out and acts like a dvi connection. I spent $70 on the kanex iAdapt and it never worked properly. I want my $$ back!!!

I had this product for about a month when the sound problems began. Initially I was using the recommended configuration. Both Video and Digital Audio ports were being run from my mac mini media center into the converter. From the converter I just ran the HDMI connector to my amp. After a month the sound began to cut out, almost like a CD was skipping randomly (except this was when playing both music and video files.) This rendered the converter unusable for the purposes of sound though. Thankfully my amp supports direct audio TOSlink from the mac mini so I used the Audio TOS cable that Kanex shipped with to connect the mac mini to directly to the amp.

That got me going for another two months at which point the sound just died again. At this point the main culprit is most likely the TOSlink cable that the adapter ships with, maybe that's poor quality and who knows - maybe that was the cause of the initial sound cut-out problems?

In any case - I've had zero problems with the Mini-display -> HDMI video functionality of the tool (which is why I'm giving it the extra star) but really - for a freaking *converter* that costs $70+ there should be greater reliability or manufacturing quality.

Additionally - while I know this product is supposed to be "so obvious to use that no documentation is needed" - the fact that it ships with zero documentation is highly disconcerting, especially when things start to break and you're attempting to troubleshoot. Who knows - maybe the "known issues" section of that guide might get too long. For those of you looking for help you can find what little documentation is available at:

This product worked great for about 3 weeks, then it just stopped working. I plugged in my computer one morning only to find that nothing happened, I tried it with a different computer and still, nothing. It was great while it worked, the whole 3 weeks....

I bought this adapter to allow my MacPro to stream Netflix and other movies sources to my HD-tv's HDMI input. The sound comes through beautifully as advertised. Unfortunately, the video stream is so dark that no amount of adjustment on the tv could compensate enough to see a good picture. As a result, this adapter sits useless by my TV, while I watch Netflix on my computer. I would not recommend at all.
