Dead pixel is an area on the Liquid Crystal Display (LCD) monitor which is not performing as expected. Usually the problem that leads to dead pixels is that the liquid flowing through the display is not flowing through that pixel properly. In this article, we will take a look at how to identify the dead pixels and then try to make those pixels into working condition.
First of all, see this video about dead pixels on LCD monitors:
IsMyLcdOK is a nifty portable software which does what its name implies. It helps you find all the dead pixels on the LCD monitor. Although it’s just 25 KB in size but it checks the LCD quite effectively. Basically, it will make all the screen of one color so that you can spot the dead pixel.
Just run the utility and press the desired number for painting the screen with corresponding color. Make sure that you have gone through all the colors to confirm all the dead pixels.
Once you have identified the dead pixels, follow the steps below to remove the dead pixels.
- Turn off the computer or LCD and make sure there is no dust on the LCD monitor
- Take a damp cloth and apply a little pressure on the dead pixel. Just make sure that you are applying pressure only on the dead pixel spot
- Turn on the computer and remove the pressure after a little while
This should remove the dead pixel and the fluid will start flowing in all the pixels of the LCD screen. Run IsMyLcdOK again and check if the dead pixels are gone.
There are several alternatives to IsMyLcdOK which can be used for the same test. If you don’t want to download anything, you can simply visit this web page and follow the instructions there to check for dead pixels. Undead Pixel is another program that not only locates the dead pixels but tries to fix them too.
