Fix A Stuck LCD Pixel

“Stuck” screen pixels are usually a white, or red, or green, or blue, colored dot on your LCD screen, that remains “stuck” (fixed) with that one color. (Where as “dead” pixels are black, and generally cannot be fixed.) stuck_pixelStuck pixels frequently fix themselves (go away) with time – be that an hour, a day, a week, or a year.

If you have grown tired of waiting, and want to try to unstick the pixel, the standard method is to use a program to “flash” colors repeatedly to the area, forcing the pixel react. This is not always successful, and you may need to contact the LCD’s manufacturer, and discuss a replacement.

The program I use for this on computer monitors is UDPix (UnDead Pixel) which applies rapid display changes to a selected area for a period of several hours. You launch it, and drag a small, flashing rectangle over the problem pixel(s). You can continue using your computer while UDPix is running.

Today’s free download: UDPix
“UDPix is a simple program that helps you locate and possibly fix stuck pixels in your LCD display.”

For those of you who might want it, there is a good tutorial for using UDPix here. [note: I really do not recommend the alternative method mentioned at the top of the article under the title “UPDATE 1:”]

Related download: I have not personally tried this application yet, but another such tool is JScreenFix.
“JScreenFix is a software solution that can fix stuck pixels, reduce screen burn-in and improve the quality of images displayed on a screen.”

  1. TechPaul,

    I have experienced the “dead pixel” problem and believe it or not I resolved the problem by taking a pencil with a good eraser on it and tapped quickly (one time)directly over the dead pixel. I found this option somewhere on the internet and was skeptical; BUT,it worked for me. It’s sort of my wife’s way of resolving it; “if it is not working, hit it with a hammer”.

    • Rick,
      The method you described is sometimes referred to as “reseat”-ing, and yes, it sometimes does bring “dead” pixels “back to life” (chances depend on why the pixel is dead).
      I consider it a “method of last resort”, and only try it if the dead pixel is in such a location that ignoring it is not reasonable, as there is risk of causing damage.
      Different manufacturers have different policies, but dead pixels are a legitimate cause for warranty replacement.
