Having problems with your PC Desktops ?

Monitor displays a black half circle 1.5 inch diameter in upper left conrner of screen.

\015 My monitor suddenly displays a black half circle about 1 inch in diameter in the upper left corner of the screen. It completely covers the back arrow icon and part of the forward icon in Interner Explorer. Of course it is present at all times, not just when I am using Explorer.\015

Answers :

Depending on the age of the monitor, this could be a symptom of a failing LCD display (or CRT tube, if you're using one of the older styled big ones). one way to test for sure though, is if you have access to another computer (whether it be desktop or laptop, shouldn't matter) and hook it up to that one and see if the same thing happens. If it does, then you know that your monitor is at fault. If you are within manufacturer's warranty you can usually get it repaired through your place of purchase, or directly with the manufacturer themselves, but if not, then repairs are usually not worth it, and will probably cost more than the monitor is currently worth.

Faulty Monitor? I bought one of these Xerox flat panel 19 inch monitors to replace my convention Sony unit about 4-5 months ago. It has worked just fine until about 7 days ago. Are there any known problems with these Xerox units? I turn my computer off during the day, when I am at work. I also turn my computer off during the night when I am asleep. At those night times I also turn the 'blue power button' on the monitor off as well, as it will flash annoyingly in the room if left in the 'stand
