* [LIGHT MODE] is available when [OFF] is selected for [CONSTANT BRIGHTNESS].
* [REF. LIGHT ADJUST] is available when [NORMAL] is selected for [LIGHT MODE] and [OFF] is selected for [CONSTANT
BRIGHTNESS].
TIP:
• Brightness normally decreases with use, but by selecting [CONSTANT BRIGHTNESS] mode, sensors inside the projector detect
brightness and automatically adjust the output, thereby maintaining a constant brightness throughout the life of the light module.
However, if output is already at its maximum, brightness will decrease with use.
For this reason, when using multi-screen projection, it is recommended to adjust the brightness to a slightly lower level, then
setting the [CONSTANT BRIGHTNESS] mode to [ON].
[REF. WHITE BALANCE]
This feature allows you to adjust the white balance for all signals.
The white and black levels of the signal are adjusted for optimum color reproduction.
Uniformity is also adjusted when the redness (R) and blueness (B) of the white color in the screen's horizontal (left/
right) direction are uneven.
CONTRAST R/CONTRAST G/CONTRAST B ���������������These adjust the picture's white color�
BRIGHTNESS R/BRIGHTNESS G/BRIGHTNESS B ����These adjust the picture's black color�
UNIFORMITY R ���������������������������������������������������������The further this is set to the + side, the stronger the redness on the left side
UNIFORMITY B ���������������������������������������������������������The further this is set to the + side, the stronger the blueness on the left side
33 "3-6. Changing LIGHT MODE/Checking Energy-Saving Effect Using LIGHT MODE
The light module luminance (brightness) will become 100% and the screen will turn bright.
By controlling the brightness and fan speed according to the selected setting, energy can
be saved and motion noise and the power consumption can be lowered.
The mode optimizes the service life of the optimal parts. The brightness is about 30% of
NORMAL.
[CONSTANT BRIGHTNESS] mode will be canceled.
Maintains the brightness that is in effect at the time [ON] is selected. Unless [OFF] is se-
lected, the same settings will remain in effect even when the projector is turned off.
• To re-adjust the brightness, first turn this setting OFF before making further adjustments.
NOTE:
• [CONSTANT BRIGHTNESS] mode is a function used to maintain the brightness at a constant
level. Color will not be fixed.
Brightness can be adjusted in 1% increments from 30 to 100%.
When several projectors are used for multi-screen projection, the brightness can be ad-
justed individually on each projector.
