Color Management
In most installation situations, color management is not necessary, such as in
classroom, meeting room, or lounge room situations where lights remain on, or
where building external windows allow daylight into the room.
O nly in permanent installations with controlled lighting levels, such as boardrooms,
lecture theaters, or home theaters, should color management be considered. Color
management provides fine color control adjustment to allow for more accurate color
Proper color management can be achieved under controlled and reproducible viewing
conditions. Use a colorimeter (color light meter) and provide a set of suitable source
images to measure color reproduction. These tools are not provided with the
projector, however, your projector supplier should be able to give guidances or send
an experienced professional installer for you.
The Color Management function provides six sets (RGBCMY) of colors to be
adjusted. You can select any of them to adjust its color range and saturation.

only pure red is selected. Increasing its range will
include both the red color close to yellow and red
color close to magenta.

adjustment made reflects to the image immediately. For example, if you select
Red and set its value at 0, only the saturation of pure red will be affected.

*About saturation
It is the amount of that color in a video picture. Lower settings produce less saturated
colors; a setting of “0” removes that color from the image entirely. If the saturation is
too high, that color will be overpowering and unrealistic.
The function is accessible through the remote control.
• N oise Reduction
Reduces electrical image noise caused by different media players. The higher the value,
the less the noise.
