▪ W/B adj. Objective & How-it-works 

- Objective: To reduce each Panel’s W/B deviation 
- How-it-works: When R/G/B gain in the OSD is at 192, it means the panel is at its Full Dynamic Range. In order to 

prevent saturation of Full Dynamic range and data, one of R/G/B is fixed at 192, and the other two is 
lowered to find the desired value.   

-Adj. condition : normal temperature 

 

1) Surrounding Temperature: 25±5℃ 

 

2) Warm-up time: About 5 Min 

 

3) Surrounding Humidity: 20% ~ 80%
