Dual-Link
To the impulsive buyers who might order the screen after the previous paragraph: check if your video card is compatible with the display. Talking to people around me, I noticed that there was a bit of confusion about what ?Dual-Link? is. Many people are mixing up Dual-Link and Dual-DVI.
Dual DVI means that there are two DVI connectors on your graphics card. Each of these connector might be Dual-Link or not. Explained with plain words, the single-link DVI connection can carry enough information to build a 1920x1080 pixels image at 60hz. Dual-link DVI doubles the bandwidth and therefore allows a 2560x1600 image to be send from the computer at a frequency of 60hz (or 60 images per seconds).
A single dual-link DVI connector is required to use the maximum resolution of this screen. If a dual-link is not present, a 1280x1024 pixels image will be displayed. Make sure that you connect the monitor on the proper DVI connector as most dual-link cards have two DVI connectors, one of which is not dual-link capable. Note that it is possible to get a dual-dual-Link graphics card capable of driving two 3007WFP monitors (!).
One last point: we used a 7800GT. While all the 7800 chips are dual-link capable, it is something that?s enabled or not by the card manufacturer. Make sure that your card is dual-link capable.
