Question about Mitsubishi Diamond Pro 2020U Monitor
For a given resolution setting the image size varies from a normal 100% to about 85% size. This happens particularly on startup or when screen goes from screensaver powerdown to active. When the screen shrinks it always brightens significantly and black levels become poor. It will switch back and forth between these 2 states (100%/normal and 85%/too bright) about evry 15 seconds to 2 minutes until the screen has been on for 1/2 hour to one hour. What is the defect and how can this be repaired. This is an otherwise very satisfactory monitor and I don't want to ditch it.
WHEN does this problem occur? Does it ONLY happen after the computer loads Windows (or another OS), or does it happen as soon as you turn the monitor on? We really need more information before we can provide specific advice or suggestions... IF this happens as soon as you turn the monitor on, switch it with a different monitor. If the problem goes away, the original monitor is defective, and probably not worth the cost of repairing it. If the problem ONLY happens after you load Windows, boot the system into Safe Mode (press the F8 key during bootup until you see the menu which allows you to select Safe Mode), then reboot and see if the problem has been resolved; simply booting into Safe Mode, then rebooting the system into Windows MIGHT solve this WITHOUT requiring you to change any system settings... IF the problem remains in Windows AFTER you've booted into Safe Mode AND rebooted back to Windows, the videocard driver might be corrupted. In that case, you'll have to reinstall the vidcard driver to correct this problem... If all else fails, it IS possible that the videocard itself is defective; if installing an updated driver doesn't work, try swapping the videocard with a different one. BE SURE to uninstall the OLD videodriver, and install the proper one for the new videocard; if you don't install the correct driver, you could create MORE problems than you have right now...

Have you tried a different cable? It could be broken.
On my Plus 91 with special software (Powerstrip) I can get the refresh rate up to 119Hz at 1024 x 768, but I use 1280 x 960 at 96Hz as it's the highest res I want to use for prolonged periods of time as 96Hz doesn't give me eyestrain no matter how long I stare at this thing.
