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 the ability to extend your display when mounting or working in an office environment where a longer reach is needed.
Kanex brings you the ideal solution by providing extension for both audio and video from any Mini DisplayPort equipped Apple computer to your Cinema Display. This extension cable optimizes quality and performance by combining USB audio with Mini DisplayPort video into a single-cable solution.

When I asked why this product would not work I was told that this product was not compatible with my Thunderbolt display and that was not made obvious at the time of order. I did not even receive an offer of a refund and have been left with a product that is completely useless to me. So Kanex, thank you for your lousy service and follow up of your products and I rate you with no stars

Kanex Extension Cable - Apple LED Cinema Display 10ft - it's working as what it suppose to do. Hook up with Previous Generation of Mac Pro with ATI Radeon 5770 mini display port and the Apple Cinema Display 27-inch. Sincerely hope that you can have an Extension Cable that support Thunderbolt Display.
