1.6.3. Signal adjustment
1.6.3.1. H.POSITION, V.POSITION
Used to adjust an incorrect image position so as to minimize no signal area on the upper left of
the screen.
[Procedure]
1. Select H.POSITION in the input memory menu.
2. Adjust the value by left/right button not to display no signal area on the left of screen.
3. Select V.POSITION in the input memory menu.
4. Adjust the value by left/right button not to display no signal area on the top of screen.
1.6.3.2. FINE (for ANALOG input)
Used to adjust so that noise on an image will be minimized. The adjusting range is -16 – 15 (-32
– 31 in S.ANALOG input).
[Procedure]
1. Select FINE in the input memory menu.
2. Adjust the value so that noise on the output image will be minimized.
If a jitter noise still remains even after H.TOTAL and FINE adjustment, adjust CLOCK RANGE
(chapter
1.6.3.11).
1.6.3.3. AMP GAIN (for ANALOG input)
Used to adjust the gain level of an analog signal in the main input. Due to uneven AD converting
levels of analog input, colors in each screen look different even if the CSC adjustment is
appropriate. It is effective in each input memory.
[Procedure]
1. Display a full-white signal through an actual input route.
2. Select AMP GAIN in the input memory menu.
3. Select AUTO GAIN and press [ENTER] button in reply to “AUTO GAIN START?” message.
4. The optimum value is automatically set. The adjustment will finish when “CALCULATE…”
indication disappears.
[When “ERROR” is displayed]
An error message is displayed if the input signal level exceeds the adjustment range i.e. the level
is too low or too high, or a full-white signal is not input. In such cases, it is necessary to input a
signal with the optimum level.
[Manual adjustment]
Normally the AUTO GAIN adjustment is recommended. In special case such as a full-white signal
cannot be input, the manual adjustment may be helpful.
1. Select AMP GAIN in the input memory menu.
2. Select MANUAL GAIN.
3. Adjust R/G/B-GAIN or R/G/B-LEVEL respectively.
[NORMAL] button can reset it to the values in AMP GAIN in the system memory (chapter
1.5.3.2, on page 48). If it has not been set, it restores the factory setting values.
