Samsung observes the specifications regarding strict
quality and reliability of LCD. But in spite of that, it is

pixels. A large number of bad pixels can cause problems in

computer performance.

dot principles:
- Bright dot : 2 or less
- Black dot : 4 or less
- Combination of Bright and Dark : 4 or less
