6.1.1 Overview

•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.
