Hey guys, I just got a LG Flatron L1720P display from Best Buy. When I plugged it in, there was a blue pixel in the upper left hand corner that appeared when it was powered on. It seems to disappear when the monitor is actually getting data to fill the whole screen, but in a 3dMark sequence for example, each time the new benchmark is started, and the screen refreshes, it shows back up for a few nanoseconds till an image is displayed then it seems to disappear. I have tried to move a solid block of color in an application over it to see if it's still there, and it seems to vanish when windows is running. Just wondering if there is a way to get rid of it because it is annoying knowing that there is a funky pixel on my screen.
 
You have what is the very bane of LCD purchasers, called a "dead pixel". Many monitors have them, and often times more than one. It is always stuck on one color, but mostly only noticeable when the screen is one solid color, like the loading times between benchmarks. I'm afraid you may be stuck with it, but it's not a huge deal.

The only known trick to removing dead pixels is to take a cotton swab and gently "massage" the area with the dead pixel. I tried this with mine, and it didn't work. A friend tried it, and it removed the dead pixel but caused more to pop up in other places. I think it's worth a shot, but be careful.
 
It does sound like a dead pixel, and IceTeaBag offers up a solution for it. However, massaging it with a cotton swab does not work all the time. If the pixel transistor is really broken, then you can't bring it back. Sometimes, the transistor's merely stuck somehow, and massaging it will bring it back.

Be careful not to massage too hard around the area, as you might inadvertently break other pixels in the process of trying to fix the other one.
