Kanex DVI and 30-inch ACD adapters attach MiniDP
Kanex today brought out a trio of display adapters to hook up older computers with Apple's newer Cinema Displays as well as newer computers to the 30-inch Cinema Display. The C247m and C247d respectively attach mini DVI and full-size DVI computers to the Mini DisplayPort jacks of either the 24- or 27-inch Cinema Displays. The two add a USB connector to pass through audio, the camera and USB functionality.
A third peripheral, the C30, works in reverse and is designed to let Mini DisplayPort Macs (or certain AMD Radeon HD 4000 cards) attach to Apple's 30-inch display and other screens that need a dual-link DVI connector. It too has USB, but primarily to power the adapter.
Only the C30 is available today and costs $99. The C247 variants ship in November and will both cost $129.
