Are they always vertial shadows, just to the right of the image/text? Could be due to a badly plugged-in VGA cable, a cheap KVM switchbox or cheap cables, or a too-high refresh rate. Possible solutions: wiggle the cable plugs, try plugging the monitor directly into the PC if you have a switchbox, or lower your refresh rate (the flicker gets annoying to me below than 75Hz though). If you have an LCD monitor and are using a VGA cable, getting a video card with DVI outputs will fix the problem too. -- Dan Nelson dnelson@allantgroup.com
