Why can't I get my Dell Latitude to output to an external monitor at 2560x1440

I've got a Dell Latitude E6520 and I'm using the E Port dock to get a DisplayPort output to plug into a Dell U2711 monitor.

The native resolution of the monitor is 2560x1440 and I'd really like to get it to that resolution.

I'm using the Nvidia X settings thing and I the highest resolution listed is 1920x1080. Is it worth hand editing the xorg.conf file maybe? Or am I just out of luck?

The graphics card (NVIDIA NVS 4200M 512MB) seems to be functioning ok. Unity and the composite effects are all working and pretty snappy.

I did have to disable something called Optimus in the BIOS but I gather this is just a power saving thing.

When I upgraded to Ubuntu 11.10 I was able to select the full resolution in the nVidia settings dialogue and everything worked perfectly.
