I have 3 Microtek c593 monitors but only one works with Windows 7. The other 2 go "out of range" at boot up. I've tried changing the refresh rate to 60 and size to 800 x 600 but it still didn't work. I finally uninstalled the Display adapter and it worked great but when I brought up Windows 7, it found new PNP drivers and reinstalled the drivers that caused the problem, (which is NVIDIA GeForce 6150SE nForce 430) and asked for a reboot which took me back to the original problem. The only differences I noticed about the Monitors are the Version Number in the Menu. The good on says Version XGA-D9E11-5515 and the 2 that don't work say XGA-D9B11-5510. If the version number is the problem how do I upgrade it?
