Windows 7 x64 now stuck on low resolution non-PNP monitor.

[Guest kmarsh8]

I recently rebooted my Windows 7 x64 system with the monitor turned off. When I turned it on, it came up at a much lower resolution.

 

Since then, I have raised the resolution as high as it will go, but 1600x1200 is very blurry on my 1920x1200 monitor. Windows 7 insists my monitor is non-PNP which is ridiculous, it is a high end monitor, a Viewsonic VP2330wb.

 

I have gone into Screen Resolution->Advanced and Windows 7 simply refuses to pick up the monitor. It insists it is a Generic non-PnP. I forced the nVidia drivers to allow non-supported resolutions, which allowed me to choose 1920x1200, which stuck after reboot. But this is a lie, the monitor is still running at blurry old 1600x1200 and is annoyingly telling me so at regular intervals.

 

I have cycled power on both monitor and the Windows 7 system. My Linux box has no problem recognizing my monitor for what it is.

 

I am running the Windows 7 provided nVidia drivers for my 8800 Ultra.

 

How do I force Windows 7 to talk PNP to my monitor?
