  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.

dot principles:

- Combination of Bright and Dark : 4 or less
