* After finishing ADC adjustment, check 64 gray
RGBW pattern.
- Color saturation
- There should not have any lack of RGBW. The
color should appear normal and sort in right order.
- Color levels should be sufficient and normal. (the
unidentified color levels on both left and right
sides should not over 8 color levels.)
