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
