Product Description

The Kanex Mini DisplayPort Extension Cable with USB is a premium grade cable designed to extend the 24- and 27-inch Apple LED Cinema Display. These immaculate LED displays by Apple include a standard cable with a fixed length, which limits the ability to extend your display when mounting or working in an office environment where a longer reach is needed. Input: Mini DisplayPort / USB

I am using these cables for the Apple 27" Cinema Display, which was introduced in July 2010 and discontinued in October 2013. Some reviewers are attempting to use this cable for the Apple 27" Thunderbolt Display (introduced July 2011 -still being sold by Apple) which I have NOT attempted, so I can not specifically address cable's functionality for Apple ThunderBolt Display, but I would suspect that it might work, though I would personally go with a specifically ThunderBolt Extension Cable, if it was me. BUT here's my experience: Using 2011 and newer MacBook Pro Computers, which have Thunderbolt Ports (which look just like Mini Display Port) the six foot Kanex Extension Cable AND the ten foot Kanex Extension Cable both worked, individually, on Thunderbolt Ported Apple Computers... BUT I discovered that IF you plug a Kanex 6' Extension Cable INTO a Kanex 10' Extension Cable, and have them BOTH (total 16 feet) connecting between Apple Cinema Display and Thunderbolt Ported Apple Computer, THEN the USB outlets in the Cinema Display do NOT show up on the Apple Computer Desktop [I had USB Memory Sticks in the Cinema Display's USB outlets, which then did NOT show up!] ! Sound still played through the Apple Cinema Display, though, which surprised me, as it's my understanding that the sound for the Apple Cinema Display comes through the USB connection (I even tried unplugging the USB cables, and the sound still played through Cinema Display!Read more ›

Bought these for my Apple Cinema Displays so i could set my laptop behind my desk so I no longer had to set the laptop on the desk and have all the wires running everywhere.

They worked exactly as expected, I was surprised Apple didn't alert me saying its not supported like the iPhone does with unsupported cables.

If you need to extend the reach of your Apple Cinema LED screen, its perfect.

Be weary, the signal can't always travel 10ft. Some cables are okay at it, like VGA, DVI, even HDMI, but this port was never made to travel that distance. My 2009 iMac couldn't do it. But the 6ft cord I got from them worked okay.

This cable works great. It gives me the much needed extension that apple should have included. Maybe a retractable cable Apple? I had a problem with the first unit and they replaced it with no delay. Great customer service and quality.

I use this with the Kanex KVM switch to control two Mac Pros (Both a decent distance from my Cinema display). Works fantastically, no problems at all. Would recommend anyone that has a MDP display to buy one.

Using it in conjunction with a StarTech.com DP2MDPMF6IN 6in DisplayPort to Mini DisplayPort Video Cable Adapter - M/F to connect my LED Cinema 24-inch to a Zotac GTX760 installed in my Mac Pro 2009 (4,1). Works perfectly in both Windows 8.1 and OS X Mountain Lion.

UPDATE 1/24/2014: The USB cable seems flaky. I had to plug in my keyboard to one of my other monitors to keep it working, and I am also getting static on audio output.

Works just as it should. Makes Apple's shortfall on the short Cinema Display cable workable. I hate using extensions, but to get any distance away from a cinema display this is a must have. Using with my Mac Pro and couldn’t be happier.

Tried this with an Apple Cinema Display.....
As others have mentioned, the Audio to the Display or Audio from a MIC in the Apple Cinema Display was completely Garbled. The Video signal looked fine..... Thus the cable needs a redesign, too bad... would have been a GREAT Price!
