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.
