JScreenFix – Fix stuck pixels and burn-in on LCD and plasma screens. How do I check for stuck pixels? JScreenFix will help fix stuck pixels on LCD screens. Most stuck pixels are fully repaired within 20 minutes. Some users have reported that JScreenFix can even fix dead pixels! Unlike other solutions, JScreenFix works on each colour cell individually in an un-coordinated fashion. This is a more effective method to repair stuck pixels and is less stressful on the screen’s power circuitry. The technique is also less likely to cause photosensitive epilepsy, a common problem when playing traditional pixel fixing videos.
