How to Fix a Dead Pixel
Lcd monitors are a great way to save space and get high resolution graphics without the bulk, or lead, of a Crt monitor. However, Lcd monitors do have drawbacks. One of these is what population call a "dead pixel." Basically, a dead pixel appears as a small black spot on your screen. A stuck pixel can also appear black, though it can also be blue, green or red, as well.
The divergence between a dead pixel and stuck pixel is subtle (that is to non-techies), but it is important to note. A stuck pixel can commonly be fixed, while a dead pixel can be the succeed of failed hardware and may not be able to be fixed. Either way, attempting the heal of your monitor, or monitors, will help you decree which it is. There are literally any ways in which to do this.

Massaging, Pressing or Tapping:
1. Turn off power to the monitor. If you are using a laptop, you'll need to turn off the entire machine.
2. Put gentle pressure on the dead pixel with your finger or the end of a pencil eraser. If you're worried about smudges or scratches, get a clean damp cloth. Protect your screen while doing this and do not apply too much pressure.
3. Turn the power back on.
4. Gently rub the spot where the dead pixel is located, until the color begins to change. You may need to do this for in any place from any minutes to any times within an hour. A divergence of this method is to moderately tap the area where the pixel is located, with a black background in place. And remember, always be gentle with the screen or you will cause more damage.
5. When the pixel is repaired, use a white background to make sure that it is the right color.
Color Flashing:
1. Download a freeware color flashing program. These are specifically designed to stimulate the dead pixel, as well as those colse to it. One such agenda is a small, rapidly flashing square, which can be dragged over the pixel.
2. Leave the agenda running for at least 1 hour. If, at the end of that hour, the pixel is still stuck or dead, you may need to use a full screen version and let it run for as much as half a day (12 hours).
It is very important to understand that none of these methods is guaranteed to work. Trial and error may give you the results that you want, but you might just be stuck with that annoying dead pixel. Also, if you're going to try to send your monitor in for change under warranty, understand that a dead pixel is not determined grounds for change by most manufacturers.
Of course, many users are not bothered by a dead pixel, especially if you have dual monitors or one large monitor and that dead or stuck pixel is just one in a sea of pixels and space. It helps, however, to start out with a quality Lcd Monitor, so make sure you buy a trusted brand. Hp Lcd Monitors, Samsung Lcd Monitors, and Sony Lcd Monitors are just a few of the reliable brands. Remember, if it's some off-name brand you've never heard of and the price seems too good to be true, it is. If you do run in to a stuck or dead pixel, try the instructions above and there's a decent opening you'll revive the pixel.
