How to Get Rid Of Black Spot on a Computer Screen
Dead pixels can be extremely distracting when you are trying to use a computer, appearing as black spots on your screen. Each individual pixel on an LCD screen is made up of three diodes -- one red, one blue and one green. If all three fail, the pixel will appear as a permanent black dot.
In some circumstances, you can bring a dead pixel back to life by using a recovery application on your monitor. Recovery applications force the pixels on your monitor to change rapidly, potentially re-awakening the faulty diodes. Alternatively, massaging a dead pixel with a soft object can sometimes fix the issue.
Using LCD Repair
Open the LCD Repair website (link in Resources).
Click “Fix My Screen.” Your browser will display a full-screen pattern of rapidly-flashing primary colors. Leave this pattern running on your screen for 10 to15 minutes.
Press “Esc” to close the pattern and return to LCD Repair's menu screen. Check to see whether or not the dead pixel is now working again.
Using JScreenFix
Open the JScreenFix website (link in Resources.)
Click “Launch JScreenFix.” The site will display a window with a rapidly-changing static-like pattern inside.
Click and drag the window over the dead pixel and then let the program run for around 10 minutes. After this time, click the “Back” arrow and then examine the dead pixel to see if the problem has been resolved.
Using Physical Pressure
Add a small piece of adhesive tape to the edge of your monitor directly above the location of your dead pixel. Next, add another small piece of tape to the edge of your monitor directly to one side of the pixel. These pieces of tape will act as co-ordinates to help you locate the dead pixel with your monitor turned off.
Turn your computer monitor off.
Take the cloth and wrap it around the eraser end of the pencil.
Push the eraser end of the pencil against the stuck pixel for around 10 seconds and then release. Repeat this motion 15 to 20 times.
Remove the tape and then turn the monitor on. Check to see if the dead pixel is working again.
