level, this is perfect for watching movies in a living room where there is a small 
amount of ambient light.
•  Cinema : With well-balanced color saturation and contrast with a low 
brightness level, this is most suitable for enjoying movies in a totally dark 
environment (as you would find in a commercial cinema). 
•  Game : Suitable for playing video games in rooms with a small amount of 
ambient light.
•  Game (Bright) : Suitable for playing video games in a bright living room.

Brightness
Adjusts the brightness of the picture. When adjusting this control, the black areas of 
the picture appear just as black and details in the dark areas are visible.
The higher the value, the brighter the 
picture, while the lower the value, the 
darker the picture. 
The function is accessible through the remote control. 
Contrast
Adjusts the degree of difference between dark and light areas in the picture. After 
adjusting the Brightness value, adjust  Contrast to set the peak white level. 
The higher the value, the greater the 
contrast.
The function is accessible through the remote control.
Color
Adjusts the color saturation level - the amount of each color in a video picture. Lower 
settings produce less saturated colors; setting to the minimum value makes the image 
black and white. 
If the setting is too high, colors on the image will be overpowering, which makes the 
image unrealistic.
Tint
Adjusts the red and green color tones of the picture. 
The higher the value, the more reddish the picture becomes. The lower the value, the 
more greenish the picture becomes.
Sharpness
Adjust to make the picture look sharper or softer.  The higher the value, the sharper the 
picture becomes. The lower the 
value, the softer the picture becomes.
The function is accessible through the remote control.
Color 
Temperature*
The options available for color temperature* settings vary according to the connected 
input signal.•  Lamp Native : With the lamp’s original color temperature and higher 
brightness. This setting is suitable for environments where high brightness is 
required, such as projecting pictures in well lit rooms.
•  Wa r m : Makes pictures appear reddish white.
•  Normal : Maintains normal colorings for white.
•  Cool : Makes pictures appear bluish 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.
The function is accessible through the remote control.

•  2.6/2.8 : Best for viewing movies which are mostly composed of dark scenes.
• Brilliant Color
This function 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. Selecting  Off

Color Management
In most installation situations, color management is not 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.
Proper color management can be achieved under controlled and reproducible viewing 
conditions. 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 give guidances or send 
an experienced professional installer for you.
The  Color Management  function provides six sets (RGBCMY) of colors to be 
adjusted. You can select any of them to adjust its color range and saturation.
1. Press  OK to display the  Color Management  window. 
2. Select  Primary Color  and use  /  to select a color from  Red, Green , Blue , 
Cyan , Magenta , and Ye l l o w .
3. Press   to select  Hue and use  /  to set its range. Increase in the range will 
include colors consisted of more proportions of its two adjacent colors. 
The illustration shows 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 select  Saturation* and use  /  to adjust its values. Every 
adjustment made reflects to the image im mediately. For example, if you select 
Red and set its value at 0, only the saturation of pure red will be affected.
5. Press   to select  Gain and use  /  to adjust its values. The contrast level of 
the primary color you just selected are affected. Every adjustment made reflects 
to the image immediately. 
6. Repeat steps 2 to 5 until you have made all of the desired adjustments.
7. When done, press  BACK to save your changes and exit.
*About saturation
It 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.
The function is accessible through the remote control.
• Noise Reduction
Reduces electrical image noise caused by different media players. The higher the value, 
the less the noise.
