The Kanex C247m is perfect for those who want to utilize the Apple Cinema Display with legacy Mac models that are equipped with a mini-DVI port.

So bring your MacBook and Mac Mini that still uses mini-DVI up to speed with this unique solution. Extend your desktop and view all your content on the beautiful Apple Cinema Display and at the same time utilize the display's built-in speakers for superb audio. It even works with the iMac 27-inch! The C247m is truly a one-of-a kind confidante.
Feature Designed exclusively for use with Apple LED Cinema Displays

With the 24- and 27-inch Apple LED Cinema Displays in mind, this adapter features a cable length of nearly 11.8 inches, effortlessly lengthening the reach of your Cinema Display.

Feature Have you heard?

Since mini-DVI does not support audio, the C247m transfers audio via USB to the built-in speakers of the Apple LED Cinema Display. Now you can watch and listen to your favorite movies, songs, or just video-chat with friends and family.

Feature Have a blast with your past Macs

Dust off the old Mac. The C247m actively converts a mini-DVI signal to a Mini DisplayPort signal. Now you can hitch your 2006–2008 MacBook or a 2009 Mac Mini to the new Apple Cinema Display with Mini DisplayPort input.

Yes, you can use the Kanex C247m for your MacBook 5,2 (mid 2009) since it has a mini-DVI port. Thank you.

The Kanex C247m will work with your 24-inch 2008 iMac and the new 27-inch Cinema Display, since your iMac has a mini-DVI port. Thank you.

Will the USB ports of the Apple LED Cinema Display work with C247m?
Yes, the C247m will allow you to take advantage of all the available USB ports on the Cinema Display

Can i use this cable with macbook Air generation before actual that have Mini Dvi ?
Please be advised that the MacBook Air first generation has a Micro DVI not a Mini DVI and therefore it will not be compatible with the C247m.

Will this product work on a 27-inch iMac?
Please be advised that this product is not compatible with the iMac 27-inch as it was designed exclusively for use with the 24 and 27-inch Apple Cinema Displays. Thank you.

Will this work with the iSight camera?
Yes this will allow you to use the full functionality of the iSight for use with webchat or videoconferencing.

Why doesn't the 27-inch accept 1080p?
The EDID of the 27-inch Apple LED Cinema Display only accepts two inputs: 1280x720 and 2560x1440. Mini-DVI can not reach a resolution of 2560x1440 so 1280x720 is the only option.

My Mac system has Mini DisplayPort that supports audio, do I still need to connect the USB?
The 27-inch Cinema Display is able to transfer audio via the Mini DisplayPort and the USB is not required. However, for devices that do not have Mini DisplayPort with audio the USB will be required.

Can I use this cable to display content on my MacBook with mini -DVI?
This cable is not bi-directional and therefore you will not be able to display anything on your MacBook.
