7. White Balance Adj.
7-1. 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
- 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.
