Hi, I have been having problems with my monitor and windows xp professional. Now before going to XP I was using 98 se, which apparently had a default refresh of 60 and I never had any problems. With Windows XP the default was like 85 and I found my monitor fluctuating on the right side of the screen (decreasing and incresing in terms of width but not height). These problems would usually cease after a few minutes and the monitor would remain stable for long periods of time. When I set the refresh rate to 60 I didn't encounter any problems at all, no fluctuations whatsoever. Now i'm sure you're saying problem solved, however, looking at my monitor manual, it does support higher refresh rates heres what it says. Standard Resolution HOR/Ver Frequency IBM/VGA 720x400 31.5KHZ/ 70Hz IBM/VGA 640x480 31.5KHz/ 60Hz VESA/75 640x480 37.5KHZ/ 75Hz VESA/85 640x480 43.3KHZ/ 85Hz Vesa/75 800x600 46.9Khz/ 75Hz . etc . VESA/85 1024x768 68.7KHz/85Hz Note: I did a clean install, and my monitor is a generic 17 inch monitor using Windos XP plug and play drivers Also I have a geforce 2 Gts 32 mb ram using the latest nvidia drivers as well I have updated to the latest via 4 and 1 drivers. Any ideas on what I should do?
