I purchased the Westinghouse 22" LCD LCM-22w3 a few years ago, and now it's been acting up on me. I just booted into Windows 7(without changing any settings), and the default resolution is 1600x1024, and it allows me to select a refresh rate of up to 85 Hz(it didn't let me do that). I usually have my resolution set to 1680x1050 with a refresh rate of 60 Hz. Now, that resolution does not even appear in the list. Does anyone have any idea of what could be the problem and how to fix it?

Edit: I am not sure if this will help, but when I go to change the screen resolution, the monitor is known as "Generic Non-PnP Monitor". It used to be referred to as "Generic PnP Monitor). I tried to disable Generic Non-PnP Monitor, but when I restart, it uses that monitor again.

Edit 2: I created a custom .inf file using Powerstrip, but that does not work either. The monitor settings are being stubborn.
