LCD bad pixels principle of the computer

Samsung observes strict specifications regarding the quality and reliability of the LCD. However, there is a small chance that a few pixels may be bad. A large number of bad pixels can cause problems with the display, but a small number of bad pixels does not generally affect computer performance.

Samsung’s quality standards for bad pixels are as follows:

•Bright dot: 2 or fewer

•Black dot: 4 or fewer

•Combination (bright and dark): 4 or fewer

Cleaning the LCD screen
