•
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.
