A stuck pixel is a bright dot of colour most noticeable when the rest of the screen is black. Stuck pixels are fairly common on high resolution LCD screens. Stuck pixels sometimes start working again with time unless they appear black on a white background, these are known as dead pixels.
The JScreenFix pixel fixing algorithm can repair 80% of stuck pixels within 20 minutes or your money back.

Dark patches on an LCD or plasma screen are the result of image persistence. Image persistence (sometimes known as burn-in) occurs if an area of the screen does not change for a long period of time. TV channel logos, for example, often leave such marks on the screen.
JScreenFix deluxe has been designed to monitor screen usage and perform equalisation negating all noticeable long term damage.
