Apple Open Box 27" LED Backlit Thunderbolt Display Box Content - Apple Thunderbolt Display, AC power cord, Printed documentationFeatures Thunderbolt technology built in - Thunderbolt I/O technology lets you move data between your devices and your computer with unprecedented speed. With two channels of 10-Gbps throughput in both directions, it's up to 20 times faster than USB 2.0 and up to 12 times faster than FireWire 800. And it allows you to connect as many as six devices through a single, compact port. LED backlighting - Full brightness with no waiting. That's the big advantage of LED backlight technology.

LED backlighting also gives you greater control over screen brightness.

The ultimate docking station - With just one cable, connect any Thunderbolt-enabled Mac and get 27 inches of high-resolution screen space, high-quality audio, a FaceTime HD camera, FireWire 800 and Gigabit Ethernet ports & a Thunderbolt port.
