If you’ve noticed a tiny discolored spot on your computer screen that just doesn’t seem to go away, chances are you have a stuck pixel.
Press the green button in the bottom right to go full-screen. The tool will load a black browser window with a square of flashing pixels. Just click the Launch JScreenFix button at the bottom of the page. JScreenFix won’t help you find a stuck pixel, but it can help you fix it.
