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.
Solved! Go to Solution.
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.
