The Atlona 6ft Mini DisplayPort + USB male to Mini DisplayPort + USB female extension cable is designed for extending Apple monitors such as the 24" Cinema Display further away from the computer. The Apple 24" only has a 5' pigtail attached which may not be long enough so this extension is perfect for connecting any Apple Laptop or Desktop to the monitor.
All Atlona cables and adapters designed for Mac users are tested at the Apple Lab in Cupertino, CA to insure compatibility among all the computers and displays.
Note: The AT13033-2 is compatible with Thunderbolt sources. It is not compatible with Thunderbolt displays.
