Using Wall Color
In the situation where you are projecting onto a colored surface such as a painted wall 
which may not be white, the Wall Color feature can help correct the projected 
picture’s color to prevent possible color difference between the source and projected 
pictures.
To use this function, go to the DISPLAY > Wall Color menu and press  /  to 
select a color which is the closest to the color of the projection surface. There are 
several precalibrated colors to choose from: Light Yellow, Pink, Light Green, Blue, and 
Blackboard.
Fine-tuning the image quality in user modes
According to the detected signal type, there are some user-definable functions 
available when User 1 or User 2 mode is selected. Based on your needs, you can 
make adjustments to these functions by selecting them and pressing  /   on the 
projector or remote control.
Adjusting Brightness
The higher the value, the brighter the image. And 
the lower the setting, the darker the image. Adjust 
this control so the black areas of the image appear 
just as black and that detail in the dark areas is 
visible.
Adjusting Contrast
The higher the value, the greater the contrast. Use 
this to set the peak white level after you have 
previously adjusted the Brightness setting to suit 
your selected input and viewing environment.
You can also adjust Brightness or Contrast by using  
BRIGHT or CONTRAST key on the remote control.
Adjusting Color
Lower setting produces less saturated colors. If the setting is 
too high, colors on the image will be overpowering, which makes the image 
unrealistic.
Adjusting Tint
The higher the value, the more reddish the picture becomes. The lower the value, the 
more greenish the picture becomes.
Adjusting Sharpness
The higher the value, the sharper the picture becomes. The lower the value, the 
softer the picture becomes.
Adjusting Brilliant Color
This feature utilizes a new color-processing algorithm and system level enhancements 
to enable higher brightness while providing truer, more vibrant colors in picture. It 
enables a greater than 50% brightness increase in mid-tone images, which are 
common in video and natural scenes, so the projector reproduces images in realistic 
and true colors. If you prefer images with that quality, select On. If you don’t need it, 
select Off.

Selecting a Color Temperature
The options available for color temperature* settings vary according to the signal type 
selected.
1.Cool: Makes images appear bluish white.
2.Normal: Maintains normal colorings for white.
3.Wa r m : Makes images appear reddish white.
*About color temperatures:
There are many different shades that are considered to be white for various 
purposes. One of the common methods of representing white color is known as the 
“color temperature”. A white color with a low color temperature appears to be 
reddish white. A white color with a high color temperature appears to have more 
blue in it.
Setting a preferred color temperature

1. Select Color Temperature and select Wa r m, Normal or Cool by pressing 
/   on the projector or remote control.
2. Press   to select Color Temperature Fine Tuning and press MODE/
ENTER. The Color Temperature Fine Tuning page displays.

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 adjusent 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  
						

							Operation 43 any image from the disc on the screen and enter the 3D Color Management menu 
to make adjusents.
To adjust the settings:
1. Go to the PICTURE menu and select 3D Color Management.
2. Press Mode/Enter and the 3D Color Management page displays.
3. Select Primary Color and press  /  to select a color from among Red, 
Yellow, Green, Cyan, Blue, or Magenta.
4. Press   to select 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 in the projected 
picture will be selected. Increasing its 
range will include red close to yellow and 
red close to magenta.
5. Press  to select Saturation and adjust 
its values to your preference by pressing  / . Every adjusent 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. Press   to select Gain and adjust its values to your preference by pressing  /
. The contrast level of the primary color you select will be affected. Every 
adjusent made will reflect to the image immediately. 
7. Repeat steps 3 to 6 for other color adjusents.
8. Make sure you have made all of the desired adjusents.
9. Press Menu/Exit to exit and save the settings.
