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 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 -- Advanced menu, highlight Color Management and

press ENTER. The Color Management page displays.

2. Highlight Primary Color and press / to select a color from among

Red, Ye l l o w , Green, Cyan, Blue, and Magenta.

3. Press to highlight Range 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.

4. Press to highlight Saturation and adjusts 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.

5. To leave and save the settings, press MENU once or EXIT twice.
