You can adjust the white ratio in factory mode (1:Calibration, 3:White-Balance).1.

Since the adjustment value and the data value vary depending on the input source, you have to 2.
adjust these in CVBS, Component 1 and HDMI 1 modes.

The optimal values for each mode are congured by default. (Refer to Table 1, 2) 3.
It varies with Panel’s size and Specication.
