What is dual link graphics card?

[Guest]

i have an Nvidia Geforce 8800 GTX 768 mb graphics card
on my Dell XPS420 desk top
i am considering purchasing Dell U2711 monitor (27") which carries res 2560 x 1440
This monitor is 'dual link'
Does this mean i connect two dvi connectors at monitor and two from graphics card?

Not 2 DVI cables, but you do need a dual-link cable.
