The Mini DisplayPort to Dual-Link DVI Adapter lets you connect the 30" Apple Cinema Display HD to a MacBook, MacBook Pro, or MacBook Air with a Mini DisplayPort. The new MacBook, MacBook Pro, and MacBook Air each have a Mini DisplayPort that allows you to connect an external display or projector using an adapter. You can use an external display as your main workspace or to extend your desktop, or you can work in mirrored mode with a projector so you can view what your audience sees. Use the Mini DisplayPort to Dual-Link DVI Adapter to connect your MacBook, MacBook Pro, or MacBook Air to a 30" display that includes a DVI connector, such as the 30" Apple Cinema Display HD, and enjoy the ultimate widescreen canvas with a 2560x1600 resolution.
