In the following simple solution, I'll show you How to Fix a Stuck Pixel on an LCD monitor. A stuck pixel differs from a dead pixel in that, in most cases, a stuck pixel can be fixed while a dead pixel cannot be fixed. A dead pixel will generally appear as a black dot that does not change color, while a stuck pixel may appear white or any other color. There are a couple of approaches to fixing a stuck pixel. One approach is the pressure method. Another approach is via visual software using quick transitioning colors.

How to test an LCD for Dead or Stuck Pixels:
- Download the Dead Pixel Buddy and run the software
- Follow the onscreen instructions to test for dead or stuck pixels
If the test reveals a colored dot on the black screen, you have a stuck pixel. If the suspicious dot does not appear on the black screen, but does appear on all other colored screens, you have a dead pixel.
Fixing a Stuck LCD Pixel Software Method:
- Download the Fix Dead Pixels tool (don't know why it is named this as you can only fix stuck pixels)
- Extract the contents and open the M4V56052.Mp4 file
- The Mp4 video file randomly and quickly changes background colors in an attempt to activate the stuck pixel. It is best to simply resize and move the video window to affect just the area of the stuck pixel. I use windows media player or quicktime to play the file in a loop
Fixing a Stuck LCD Pixel Pressure Method:
This method works by attempting to spread liquid from the liquid crystal into the stuck pixel via the use of pressure.
- Turn your LCD monitor off
- Locate a soft cloth and a ballpoint pen or other tool with a dull point. ( a stylus works well)
- Using the cloth to avoid scratching or damaging the screen, apply pressure using the pen or stylus to the stuck pixel
- With pressure still applied, turn your LCD monitor on
- Remove pressure and if your lucky, the stuck pixel will be gone
Fixing a Stuck LCD Pixel Tap Method:
This method works by attempting to spread liquid from the liquid crystal into the stuck pixel via the use of shock.
- Turn your LCD monitor on
- Set your desktop background color to black
- Locate a rounded slightly pointed object (a marker cap works well)
- Using the rounded slightly pointed object, gently tap the stuck pixel
- Gradually increase the pressure used on each tap until the pixel corrects itself
