White shading compensation

Adjusting the white shading
This is a method of combining the sawtooth shaped waveform and parabola waveform to compensate to a flatter waveform based on the respective R,
G and B waveforms of the video signal.
We recommend adjusting the R, G and B waveforms in the horizontal and vertical directions while monitoring them on the waveform monitor.
Be sure to set [DS.GAIN] and [D.ZOOM] to [OFF] before adjusting white shading.
