LCD bad pixels
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:
• B right dot: 2 or fewer
• B lack dot: 4 or fewer
• C ombination (bright and dark): 4 or fewer
Clean the LCD screen with a soft cloth dampened with
computer cleansing detergent.
Do not use excessive force. Doing so may damage the LCD screen.
