3D 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. When you select each color, you can

independently adjust its range and saturation according to your preference.

If you have purchased a test disc which contains various color test patterns and can be used to test the color

presentation on monitors, TVs, projectors, etc. You can project any image from the disc on the screen and enter the 3D

Color Management menu to make adjustments.

projected picture will be selected. Increasing its range will include red close
to yellow and red close to magenta.

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.
