I have a slight problem. I have recently got a new monitor (the same as the last one) as the old one was replaced under warranty. My system does not recognise the monitor now, and will not display at its native resolution (1680 x 1050). The maximum I can get is 1024 x768.
I have updated my graphics drivers and installed Samsung's monitor drivers, both with no luck.
Windows Vista Business 64 SP2
2x Nvidia 8800GT (In SLi)
Monitor: Samsung SyncMaster 225UW
This happened to me but only when I had the TV linked to the card without some configurations. I suggest to uninstall the nVidia drivers and boot while using the Windows default drivers. See if you can choose a bigger resolution. After that install the monitor drivers and finally the latest nVidia drivers. Do these steps in this order. 90% it will fix any problem
