Using the projector

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, Green, Blue, Cyan, Magenta and Yellow.

3. Press to highlight Hue and press /

to select its range. Increase in

the range will include colors consisted of more proportions of its two

adjacent colors.

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 Gain and adjust its values to your preference by pressing / . The contrast

level of the primary color you select will be affected. Every adjustment made will reflect to the image

immediately.

5. Press to highlight Saturation and adjust its values to your preference by pressing / . Every

adjustment made will reflect 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.

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.

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