I noticed a small dark area in my monitor.
It is not completly dark, just darker than the rest of the screen.
That spot is still readable, but it is just annoying.

Any idea what can be the problem??
It is not dirt. /forums/images/graemlins/smile.gif

What kind of monitor? LCD? CRT? Shadow mask? Aperture grill?

You were probably staring at that picture of the sun for too long and now your monitor has got a residual case of "sunspot"! I'd watch out for excess radiation and consider rubbing sunblock on the affected part of the screen. /forums/images/graemlins/grin.gif

Try degaussing your screen.

I had a TV like that once. It was only noticeable when a bright even colour was displayed. As far as I could tell it was a manufacturing defect in the phosphor that slightly affected the brightness of an area of the screen. It was a triangular shape near the top of the screen and made it look like a tornado was in the background in certain clear sky outdoor scenes. /forums/images/graemlins/confused.gif

When did you purchase the monitor?

Was it there before or just started?

If it isn't a burn problem, then it looks like your shadow mask may be loose causing a misalignment of the electron guns.

If your monitor is new enough, get it exchanged sooner than later. Check the warranty as this is a manufacturing fault.

This shows the importance of checking montitors when taking out of a box.

I've had this computer for more than a year now.

I bought the monitor at Staples and I'm not sure I can find the receipt for it anymore, now that I moved.

But that spot is very recent...

How recent from the move did the spot appear?

I have seen internal degausers not work as well as an external one. If the problem is associated to your move, you may have had the monitor packed next to a magnetic source. This magnet may have magnetized the mask to a higher level than the internal degauser will work with.

Try degaussing the screen multiple times. You can also use a strong magnet to degauss a screen by moving the magnet around the screen in a random order and slowly moving away from teh screen. This can demagnetize the mask if done properly. I have done it on TV's but never on a computer monitor.

Have you tried adjusting the H and V location of the picture to see if the area moves? It is clutching at the fact that video card may be at fault.

I moved the x and y location and the spot remains at the same place despite that the picture moves...

Degaussing does nothing.

I will try to find a magnet to see if it does anything.

So you think there is the possibility of a video card problem?? hmmm interesting.

Thanks for the sugestions.

Confirms that it is the monitor that is at fault. If the spot moved it could be signal related such as video card. As the spot stays put, the problem has to be after the video is processed.
