For users of LCD monitors, LCD after use for some time, sometimes up to a point on the screen cannot display colors properly. Point on the screen is only visible [light] the same thing when changing the monitor display though. So often reduces the quality of the display.

The point at which the screen is damaged usually called Dead Pixel or Stuck Pixel. How do I find out, and if it appears, is there any way to fix it?

Find out / Check for the Dead Pixel

In essence, to check the existence of Dead pixel is quite easy, sometimes we can immediately see on the screen, because of the color pixel that is always the same as the display screen / monitors. Or by creating a full picture of the screen with one color only, such as black or white. This way if there is a dead pixel will be clearly visible.
