Very important note about this monitor
Remember one important thing about this monitor before you buy it planning it use the 2560 x 1600 resolution........
You must have a video card that drives Dual-Link DVD-D (Digital) output. Dual-Link is a single cable and connector. Don't confuse Dual Link with Dual output (i.e. 2 DVI connectors). It's just one DVI-D connector. Also make sure it is -D for digital (not -I). DVI-I connectors are analog and not compatible. Research this carefully before buying. It's a thousand dollar monitor.
Otherwise you cannot drive the monitor at 2560 x 1600. You will only be able to get 1280 x 800 in Single-Link DVI mode.
It's really almost like 2 monitors stacked side-by-side. But with one cable and a panoramic view.
This is also true for the Apple Cinema 30 inch HD display when hooked up to a PC.
The Dell is a great monitor for sure.
