SubmenuFunctions and Descriptions
Picture ModeSelects a preset picture mode to suit your operating environment and input signal 
picture type.
The preset picture modes are described as below:
•Bright: Maximizes the brightness of the projected image. This mode is 
suitable for environments where extra-high brightness is required, such as 
using the projector in well lit rooms.
•Vivid: With well-saturated color, fine-tuned sharpness and a higher brightness 
level, Vivid mode is perfect for watching movies in a living room where there 
is a small amount of ambient light.
•Cinema (Rec. 709): Complement the worldwide HDTV standard with 
accurate color and deepest contrast at lower brightness level, Cinema 
(Rec.709) mode is suitable for playing movies in a totally dark environment, as 
if in a commercial cinema. To easily enjoy the cinematic color retrieved from 
REC. 709 standard, we recommend you shadow all possible lighting items 
except the projector (e.g. lamps, computer screen, or light coming through 
curtains) and use a standard format of 1080p image source like a Blu-ray disc 
to get the best viewing experience under this mode.
•Game: Suitable for playing video games in a bright living room.
•3D: It is optimized to bring up 3D effects when watching 3D contents.
This mode is only available when 3D function is enabled.
•User 1/User 2: Recalls the customized settings. Access the Advanced OSD 
menu and see User Mode Management for details.

darker the picture.
The function is accessible through the remote control.
ContrastAdjusts the degree of difference between dark and light 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.
ColorAdjusts 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.
TintAdjusts the red and green color tones of the picture.
The higher the value, the more reddish the picture becomes. The lower the value,

Color Temperature*The options available for color temperature* settings vary according to the 
connected input signal.
•Normal: Maintains normal colorings for white.
•Cool: Makes images appear bluish white.
•Lamp Native: With the lamps original color temperature and higher 
brightness. This setting is suitable for environment where high brightness is 
required, such as projecting pictures in well lit room.
•War 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.
The function is accessible through the remote control.
Motion EnhancerEstimates the motion changes from frame to frame and inserts and interpolated 
frame to create smoother, more fluent viewing experience of movies.
Lamp PowerSelects the projector lamp power from the following modes.
•Normal: Provides full lamp brightness.
•Economic: Reduces system noise and power consumption by 30%.
•SmartEco: Reduces system noise and lamp power consumption by up to 
70%.
If the Economic or SmartEco mode is selected, the light output will be reduced 
and result in darker projected pictures.
See Setting Lamp Power on page 63 for details.

							Menu Functions 47 Advanced...•Black Level
Sets the picture grayscale to 0 IRE or 7.5 IRE.
The grayscale video signal is measured in IRE units. In some areas which use NTSC 
TV standard, the grayscale is measured from 7.5 IRE (black) to 100 IRE (white); 
however, in other areas where PAL equipment or Japanese NTSC standards are 
used, the grayscale is measured from 0 IRE (black) to 100 IRE (white). We suggest 
that you check the input source to see if it is with 0 IRE or 7.5 IRE, then select 
accordingly.
• Gamma Selection
Gamma refers to the relationship between input source and picture brightness.
•1.6/1.8/2.0/BenQ: Select these values according to your preference.
•2.1/2.2: Increases the average brightness of the picture. Best for a lit 
environment, meeting room or family room.
•2.3/2.4: Best for viewing movies in a darkened environment.
•2.6/2.8: Best for viewing movies which are mostly composed of dark 
scenes. 
• 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.
• Color Temperature Fine Tuning
Allows you to manually adjust the pre-defined color temperature modes:
1. Press OK to display the Color Temperature Fine Tuning window.

Advanced...• 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.
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.
1. Press OK and 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 in the projected 
picture will be selected. Increasing its range will include red close to yellow 
and red close to magenta.
4. 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.
5. 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.
6. Repeat steps 2 to 5 for other color adjustments.
7. Make sure you have made all of the desired adjustments.
8. Press OK and BACK to exit and save the settings.
