I just got a Compaq Qvision 210 free from a friend. Everything displays correctly but it is somewhat blurry. The resolution is at 1280 X 1024. It seems like there are ghosted images to the right of everything.....they are very faint but are causing it to be slightly blurry. What is causing this.....I already tried changing the refresh rate but that did not help any. Could it be a problem with the monitor?
