LCD bad pixels principle of computer
• 
  Samsung observes the specifications regarding strict 
quality and reliability of LCD. But in spite of that, it is 
inevitable that there might be a small number of bad 
pixels. A large number of bad pixels can cause problems in 
appearance, but a small number of pixels doesn’t affect the 
computer performance.
  Therefore Samsung observes and manages the following 
dot principles:
  - Bright dot : 2 or less 
- Black dot  : 4 or less 
- Combination of Bright and Dark : 4 or less
Instructions for Cleaning the LCD
Clean the LCD panel with a soft cloth lightly moistened with 
computer cleansing detergent moving in one direction. 
Cleaning the LCD panel with excessive force can damage the 
LCD.
