I just bought a U2412M 1920 x 1200 monitor.
My system is a Windows 7 64-bit with an Nvidia GTX 260 video card running the latest Nvidia drivers.
When I first attached the monitor it was only showing a Generic PnP monitor in the device manager.
So I installed the driver that came with the monitor, and it then showed a Dell U2412M(Digital) monitor in the device manager.
The problem is when I go to change the resolution it says that the display is a Philips 170B2 (?) monitor and it won't let me set a resolution above 1280 x 1024. This is the same monitor it thought it had before I installed the driver. It's like the driver didn't change anything.
When I display the driver file details it shows the following 2 files:
The GTX 260 has a maximum display resolution of 2560x1600, so that shouldn't be the issue.
Please help or I'll have to return the monitor.
Okay, even though I've been working on this for a couple of hours I knew as soon as I posted I'd figure it out ;-)
It was the KVM switch I was using. Apparently 1920 x 1200 exceeded it's max bandwidth, which caused all of the strange problems listed above.
As soon as I connected the monitor directly to my comp, it worked great, even without installing the driver.
Thanks for posting the answer to the problem.
