7. Manual ADC Adjustment
(Component 1, RGB)
[Caution]
- Do not connect external input cable
- Adjustment result is applied to SET On/Off later.
* Adjustment is done using internal ADC, so input signal is not
necessary.
7-1. COMPONENT ADC (SD / HD)
(1) Convert to Component1 input source.
(2) Press ADJ key on R/C for adjustment.
(3) Enter Password number. The value of Password is “0 0 0
0”.
(4) Select “0. ADC calibration” by using D/E(CH +/-) and press
ENTER(V).
(5) Start ADC adjustment by using F/G(VOL +/-) or press
ENTER(V).
(6) ADC adjustment is executed automatically .
When ADC adjustment is finished, this OSD appear.
7-2. RGB input ADC
Auto RGB Gain/Offset Adjustment
(1) Convert to PC in Input-source
(2) Press ADJ key on R/C for adjustment.
(3) Enter Password number. The value of Password is “0 0 0
0”.
(4) Select “0. ADC calibration” by using D/E(CH +/-) and press
ENTER(V).
(5) Start ADC adjustment by using F/G(VOL +/-) or press
ENTER(V).
