No picture...
But I just got a Dell U3011 30" display. The main reason to buy is the 2560x1600 resolution. I have been using an Apple monitor of the same size and resolution with my Mac Pro. Now one of the PCs is hooked up to this new Delll monitor.
When I install the monitor, it couldn't display at the native 2560x1600 properly, with some missing or messed up pixels, etc... But once I switched to the DVI cable that came with the monitor, then everything worked beautifully. So the DVI cable I had before was too shitty!!!
