Fix A Stuck Pixel

My two month old Vostro A90 recently suffered from three stuck white pixels. Stuck pixels, unlike dead pixels, are fixable. A dead pixel is when all three sub-pixels are permanently off, producing a permanently black pixel. A stuck pixel has one of more sub-pixels always on or always off displaying a white, green, blue or red color.

If your pixel is displaying a color this guide will help you fix it without having to resort to rubbing it back to life.


Before You Can Fix The Stuck Pixel:
Make sure your monitor will not shut off due to inactivity and that your computer sleep function is disabled.

You can find these settings under System>Preference>Power Management


Also turn off your Screensaver.

You can find these settings under System>Preference>Screensaver

- click launch application to begin the fix

A pop window will appear.

- hit F11 key to set the window in fullscreen mode (on the mini9/vostro a90 F11 is the Fn+z keys)

Allow the program to run for 20 minutes to 2 hours depending on the severity of the problem and the number of stuck pixels. I ran the program for about 20 minutes and all three pixels became unstuck.
