If you notice some spots on your screen that are not caused by dust or stains, then your screen may have some stuck pixels which can be very annoying.

A stuck pixel is a conspicuous dot of color that fails to change when the neighboring pixels change. Such pixels become very noticeable when the screen turns black.

If the stuck pixels are not as a result of defects in the screen, then JScreenFix can fix the problem. It works by flushing the affected area with hundreds of different colors every minute. This way, it takes only some few minutes to unstick the pixels.
