Too much rubbing can damage even more pixels on your screen and lead to serious problems. If none of the solutions work, the best way out is to contact a specialist.

DPTF assumes the same process as its competitor apps, using a series of solid color blank outs on your screen to reveal damaged pixels.
It also can help you identify stuck pixels by showing a series of flashing screens. Use the Check Dead Pixels function to look for any dead pixels on your display. If you spot some, switch to Fix Dead Pixel , which displays colored noise and bands of different colors over a set period.
The developers recommend that you let DPTF run for at least 10 minutes to fix all of the pixels, but we had better results when we left it running for a couple of hours, so it had time to fix all of the dead pixels.
Step 1: Open your favorite browser and navigate to the JScreenFix homepage. PixelHealer Windows PixelHealer is an entirely free application from Aurelitec that fixes pixel problems. You should see a light white rippling effect appear around the point of contact. Try to apply pressure only to the stuck pixel and not the surrounding area.
Remove the object after a few seconds. If the pixel is still stuck, you can repeat the pressure, or proceed with using heat; if it isn't stuck, however, shut down your monitor immediately and leave it off for at least one hour.
Dampen a washcloth with hot water. If you can, heat water on the stove until it's just beginning to show air bubbles at the bottom of the container around degrees Fahrenheit , then put the washcloth in and dump the hot water over the washcloth. Cover your hands. You don't want to burn your fingers in the next steps, so use oven mitts or a heavy-duty washcloth.
Seal the hot washcloth in a plastic sandwich bag. This will protect the monitor from moisture. Make sure the seal is completely closed. Hold the bag against the stuck pixel. Applying light pressure in this manner should loosen the pixel's internals, potentially unsticking it in the process.
Make sure not to hold the bag against the pixel for more than a few seconds at a time. Review your pixel. If it's been fixed, you're done.
If not, there isn't much else you can do without help from a professional repair service, so either take your monitor into a repair department or allow the pixel to unstick itself with time. You can also try using software again. I accidentally broke my laptop a few days back. Half of the screen is white, two portions of it gray, some areas black, and others with color pixels.

How should I remove them? You can try JScreenFix. If you don't know what it is, you can look it up on the internet.
