• GAMMA: The default gamma setting (2.2) is correct for almost all signals and
conditions. If excess ambient light washes out the image and it becomes difficult or
impossible to see details in dark areas, lower the gamma setting to compensate. This
will improve contrast while maintaining good details for blacks. Conversely, if the image
is washed out and unnatural, with excessive detail in black areas, increase the setting.
Again, good gamma improves contrast while maintaining good details for blacks and
whites.
• AGC (Automatic Gain Control): AGC increases the brightness of dark signals
automatically. To enable AGC, set it to ON. To disable it, set it to OFF.
• R/G/B GAIN: Use the Gain controls in the ADVANCED SETTINGS sub-menu to
correct color imbalances in the bright areas of the image. A good way to do this is to
use a test pattern consisting mostly of solid white areas, such as an 80 IRE “window”
pattern. If the white areas contain traces of red or blue, decrease the Gain for that
color.
• R/G/B OFFSET: Use the Offset controls in the ADVANCED SETTINGS sub-menu to
correct color imbalances in the dark areas of the image. A good way to do this is to use
a test pattern consisting mostly of dark gray areas, such as a 30 IRE “window” pattern.
If the gray areas contain traces of red or blue, decrease the Offset for that color.
POS./SIZEUse the controls in the POS./SIZE menu to fine-tune the displayed image position and
size.
To return all POS./SIZE menu settings to their factory-default values, press RESET on the
remote control unit with the menu on-screen. Or, press or repeatedly to highlight
RESET in the menu, then press the ACTION ( ) button.
The CinemaWall memorizes position and size settings separately
for different input signal formats. Adjustments for component
signals are memorized for 525 (480) / 60i · 60p, 625 (575) / 50i ·
50p, 1125 (1080) / 60i · 50i · 60p · 50p · 24p · 25p · 30p · 24sF,
1250 (1080) / 50i, 750 (720) / 60p · 50p each. RGB/PC/Digital
signals are memorized for each frequency.
