10-2. LCD RGB Offset Adjustment
Adjusting method:
1. Adjust LCD "RGB offset" so that the amplitude of the CL173
waveform is 7.3 V ± 0.3 Vp-p.
CL173 waveform
10-3. LCD Gain Adjustment
Adjusting method:
1. Adjust LCD "Gain" so that the amplitude of the CL173 wave-
form is 4.0 V ± 0.1 Vp-p.
Note:
10-2. LCD RGB Offset adjustment should always be carried
out first.

10-4. LCD Blue Brightness Adjustment
Adjusting method:
1. Adjust LCD "B Bright" so that the amplitude of the CL171
waveform is VG + 0.2 ± 0.05 Vp-p with respect to the CL173
(VG) waveform.
Note:
10-2. LCD RGB Offset adjustment and 10-3. LCD Gain ad-
justment should always be carried out first.
