Color Management
In most installation situations, color management will not be 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.
Only 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 reproduction, should you require it.
Proper color management can only be achieved under controlled and reproducible viewing conditions.
You will need to 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 provide you with suitable guidance, or even an experienced professional
installer.
The 3D Color Management provides six sets (RGBCMY) of colors to be adjusted to favorite colors.
When you select each color, you can independently adjust its color range and saturation according to
your preference.
To adjust and store the settings:
1. In the Picture menu, highlight Advanced... and press MODE/
ENTER. Then, highlight 3D Color Management and press
MODE/ENTER. The 3D Color Management page is displayed.
2. Highlight Primary Color and press / to select a color from
among Red, Green, Blue, Cyan, Magenta, and Yellow.
3. Press to highlight Hue and press / to select the color range
you wish to make adjustment. The bigger the range, the more
proportions of its two adjacent colors the color contains.
Please refer to the illustration to the right for how the colors relate
to each other. For example, if you select Red and set its range at 0,
only pure red is selected. Increasing its range will include both the red color close to yellow and red
color close to magenta.
Press to highlight Saturation and adjust the color saturation level by pressing / .
If you select Red and set its range at 0, only the saturation of the pure red will be affected.
Saturation 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.
4. To leave and save the settings, press MENU/EXIT.
