Making Detailed Adjustments

Use the RGBCMY settings to adjust the hue, saturation, and brightness of the six color 
components (red, green, blue, cyan, magenta, yellow). After adjusting each color, press 

Esc

 to move to another menu option. You can also access this setting by pressing the 

RGBCMY

 button on the remote control. See page 31 for more information. 

■ Gamma

Note: This setting cannot be used when the Color Mode is set to x.v. Color (see page 29).

You can select from five gamma settings (2.0 to 2.4) or customize your own setting from 
your image or a displayed graph. Lower values will increase the contrast of dark areas, but 
tend to blur the bright areas. Higher values will darken the light areas.

You can also access this setting by pressing the 

Gamma 

button on the remote control. 

See page 30 for more information.

■ Contrast Enhancement

Note: This setting cannot be used when the Color Mode is set to x.v. Color (see page 29).

This setting automatically enhances contrast by calculating based on the current contrast. 
You can select from 3 levels of contrast enhancement.

■ Color Gamut

Note: This setting can be used only when the Color Mode is set to Natural (see page 29).

Select the setting that matches the video standard of the equipment you have connected. 
Select 

SMPTE-C

 for the American broadcast standard, 

EBU

 for the European broadcast 

standard, or 

HDTV

.

In addition to the settings described previously, you can adjust the Tracking and Sync settings 
for analog RGB computer images. Normally, these settings are adjusted automatically by the 
projector. If you notice that the image is blurry or contains dark vertical bands, you may need 
to adjust the settings yourself.

■ Auto Setup

Leave this setting on so that the projector automatically adjusts the tracking, sync, and 
position of the image.
