sync signal to the G (Y) IN connector.
• When inputting the computer signal shown in item
No. 28, set the H SIZE, H SHIFT, V SIZE and V
SHIFT to the standard (00) and set ZOOM to 1 in
the PIC SIZE menu, or the picture might oscillate.

Adjusting the Picture

While watching the picture, you can adjust contrast,
brightness, chroma, phase, and so on, to suit your
taste. The adjustments can be carried out for each
input signal separately. You can also store the
adjusted levels in memory.
Adjusting the Contrast, Brightness,
Chroma, and Phase, etc.
Press MENU so that the main menu appears on the
monitor screen and select "CONTRAST",
"BRIGHTNESS", "CHROMA", "PHASE",
"PICTURE AGC", "COLOR TEMP" or
"SHARPNESS" from the PIC CONTROL menu with
M/m.
CONTRAST
Select "CONTRAST" with M/m and press ENT.
Adjust the contrast with M/m in the range from MIN
(0) to MAX (+100).
M: to increase picture contrast
m: to decrease picture contrast
BRIGHTNESS
Select "BRIGHTNESS" with M/m and press ENT.
Adjust the brightness with M/m in the range from
MIN (–50) to MAX (+50).
M: to make the picture brighter
m: to make the picture darker
CHROMA
Select "CHROMA" with M/m and press ENT.
Adjust the chroma with M/m in the range from MIN
(–50) to MAX (+50).
M: to increase color intensity
m: to decrease color intensity
Adjusting the Picture
PHASE
Select "PHASE" with M/m and press ENT.
Adjust the phase with M/m in the range from MIN (–
50) to MAX (+50).
M: to make overall picture greenish
m: to make overall picture purplish
Automatic Brightness Control –
Enhancing the Image Contrast
If the average brightness of the image is low, the
system can automatically raise the contrast level to
enhance the brightness. This function works well for
displaying dark images.
Select "PICTURE AGC" with M/m and press ENT.
Set PICTURE AGC to ON or OFF with M/m.
COLOR TEMP (Color Temperature)
Set the color temperature. You can select HIGH or
LOW, or adjust each gain more precisely. Up to six
adjusted color temperatures can be registered. You
can rename them (up to six characters in length).
1
Select "COLOR TEMP" with M/m and press
ENT.
2
Select the color temperature with M/m and press
ENT.
HIGH: to set the color temperature to high
LOW: to set the color temperature to low
1 – 6: to set the gain more precisely
When you select HIGH or LOW, the menu returns
to the PIC CONTROL menu.
When you select "1" to "6"
When you select "1" to "6", the following menu
appears on the monitor screen.
