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 people 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 difference between a dead pixel and stuck pixel is subtle (that is to non-techies), but it is important to note. A stuck pixel can usually be fixed, while a dead pixel can be the result of failed hardware and may not be able to be fixed. Either way, attempting the repair of your monitor, or monitors, will help you decide which it is. There are actually several 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 anywhere from several minutes to several times within an hour. A variation of this method is to gently 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 around it. One such program is a small, rapidly flashing square, which can be dragged over the pixel. 2. Leave the program 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 replacement under warranty, understand that a dead pixel is not considered grounds for replacement by most manufacturers.
Of course, many users are not bothered by a dead pixel, especially if you have dual LCD 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 purchase 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 chance you’ll revive the pixel.
