Picture Mode
Selects 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.
• Graphic (sRGB): This mode is best for making a still-
image presentation when your presentation slides use 
mostly graphics and minimal text. A small amount of 
ambient light is required.
• Motion Video: This mode is best for playing a video clip 
in your presentation. A small amount of ambient light is 
required.
• Lectures: This mode is best for making a presentation 
when your presentation slides use mostly text and 
minimal graphics. A small amount of ambient light is 
required.
• Cinema (Film): With well-balanced color saturation and 
contrast with a low brightness level, this is most suitable 
for enjoying movies at home where there is a small 
amount of ambient light.
• Vivid Color: Maximizes the visual effects and displays 
images in bright and vivid colors.
• User: Recalls the customized settings. Access the 
Advanced OSD menu and see User Mode 
Management for details.

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.
Color Enhancer
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.
“Color Enhancer” is not supported in the RGB color system.
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.
“Tint” is not supported in the RGB color system.
Pixel Enhancer
Detects the change in color between an object and its 
background to produce a sharpened image of crisp edges and 
enhanced surface textures.
The higher the setting, the sharper the image reveals.
The lower the setting, the tenderer the image reveals.
Color 
Temperature*
The options available for color temperature* settings vary 
according to the connected input signal.
• Normal: Maintains normal colorings for white.
• Cool: Makes pictures appear bluish white.
• 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.
*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.

LED Mode
Select the projector lamp power from the following modes.
• Normal: Provides full lamp brightness.
• Economic: Reduces system noise and lamp power 
consumption by 30%.
If the Economic mode is selected, the light output will be 
reduced and result in darker projected pictures.
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 you to check if the input source is with 0 IRE or with 
7.5 IRE, and then make your selection accordingly.

• Gamma Selection
Gamma refers to the relationship between input source and 
picture brightness.
• 1.6/1.8/2.0/2.1/BenQ: Select these values according to 
your preference.
• 2.2/2.3: Increases the average brightness of the picture. 
Best for a lit environment, meeting room or family room.
• 2.4: Best for viewing movies in a dark environment.
• 2.6/2.8: Best for viewing movies which are mostly 
composed of dark scenes.
• 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   to display the Color Management window.
2. Select Primary Color and use  /  to select a color 
from Red, Green, Blue, Cyan, Magenta, and Yellow.
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 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.
5. Press  to select Saturation* and use  /  to 
adjust its values. Every adjustment made reflects 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.
6. Repeat steps 2 to 5 until you have made all of the desired 
adjustments.
7. When done, press   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.
• Noise Reduction
Reduces electrical image noise caused by different media players. 
The higher the value, the less the noise.
• Film Mode
Enhances picture quality when projecting composite image from 
a filmsourced DVD or Blu-ray Disc. Setting Off disables the 
function.
