New monitor resolution problem.

[jcmack13]

Just got a Samsung 990DF monitor capable of 1600x1200 resolution and higher and hooked it up to my gf's laptop, which she is letting me use because mine just died. However, the maximum resolution I can set it on is 1280x1024. Is this a problem with her laptop's video card, or am i a n00b moran and there is an easy way to fix this?

Sorry if this gets asked a lot. the latpop is a Dell Inspiron 2650 if that's any help. Thanks.
