I just got my new U2711 monitor on an Intel Sandy Bridge desktop (integrated) card. I'm using the dual link DVI cable but the highest mode I can set from GNOME 3 system settings display is 1680x1050 pixels.
I changed that to the VGA cable and now I have 2048x1152 pixels. Still, it's about 500 pixels short of native resolution and that kind of sucks.
So I wonder if anyone have any smart suggestions?
