24" LCD, 1280X1024 ISSUE

[setter]

Im running A 24" Benq FP241W lcd monitor (1920x1200), gtx 470 sli, win 7 64 hp, ive been trying to run 3d mark vantage on this system, however when i load up vantage, it wont run, get the message "Required resolution 1280x1024 is not supported". Ive had a look in the res settings and this res isnt available, im using dvi, would changing to vga allow this res?

EDIT: Sorry for caps in title.

Are you running the driver for the monitor or just the Generiv Monitor driver?

If it is the latter then this may explain the lack of resolution support.
