I have a brand new Dell Precision M90 wit a NVidia Quadro FX 2500M graphics card and is running the 6.14.11.119 NVidia Driver released on 4/28/2007 (I thought that downloading this driver might solve my problem....but it did not).  The problem is that my native resolution is set to 1440*900 and I cannot set my screen resolution higher.  My colleague has exactly the same system, but his native resolution is set to 1920*1200 Pixels.

 

Any ideas out there on how to correct this?
