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 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 un–stick 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.”

• About Tech Paul
I am a Retired computer & network technician. I used to think the machines were pretty cool. Now I don’t.
They’re anything but.
I regularly posted how-to’s and tricks & tips and general computing advice here starting in 2007. (Use the Search tool to find answers. But be aware, many are rather dated.) Sometimes I answered (your) specific questions in an article if I believed the answer was generally helpful to “everyone”. All the writing you see was my own, typos and all. There always is/was an implied “IMHO” in what you see here.
Note: You are responsible for using this blog and its content. I am in no way liable for any losses caused by user error, viruses and/or other malware, hardware or software failure, or any other conceivable reason.
