4-5. White Ratio (Balance) Adjustment
You can adjust the white ratio in factory mode (1:Calibration, 3:White-Balance).
Since the adjustment value and the data value vary depending on the input source, you have to
adjust these in CVBS, Component 1 and HDMI 1 modes.
The optimal values for each mode are configured by default. (Refer to Table 1, 2)
It varies with Panel’s size and Specification.
