Today I found a useful plugin for google chrome which will fix the stuck pixels on your LCD screen without much effort. A stuck pixels are small dots on your screen which will not change its colour even though it should. Rubbing screen to fix this problem might harm your display sometimes, but this software method is 100% secure. Please note that all the stuck pixels cant be repaired using this software/addon.
Just install the this LCD Fixer plugin from google chrome webstore. You may need to run LCD fixer for upto an hour for it to fix stuck pixels. You can pressF11 button to run it on full screen which may be more effective. You have to close this program manually once it runs for an hour.
