Plugging directly into a 'normal' DVI adapter ie single-link DVI will not support the display's native resolution of 2560x1600. Single-link adapters will instead deliver a maximum of half the supported resolution, 1280x800. Single-link adapters include the typical Apple-style DVI>MiniDP adapter dongle most are used to using..

So if anyone feels like giving the video group a christmas present of this pricey adapter cable, that'd be really great! It would be kept with the monitor. 

Best,
