							Operation 31 6. To reduce size of the picture, press Mode/Enter to switch back to the zoom in/out 
functionality, and press AUTO to restore the picture to its original size. You can also 
press   repeatedly until it is restored to the original size.
The picture can only be navigated after the picture is magnified. You can further magnify the picture 
while searching for details.
Selecting the aspect ratio
The aspect ratio is the ratio of the image width to the image height. Most analog TV and 
computers are in 4:3 ratio, which is the default for this projector, and digital TV and DVDs 
are usually in 16:9 ratio.
With the advent of digital signal processing, digital display devices like this projector can 
dynamically stretch and scale the image output to a different aspect than that of the image 
input signal. 
To change the projected image ratio (no matter what aspect the source is):
1. Press Menu/Exit and then press  /  until the DISPLAY menu is highlighted.
2. Press
  to highlight Aspect Ratio.
3. Press  /  to select an aspect ratio to suit the format of the video signal and your 
display requirements.
About the aspect ratio
In the pictures below, the black portions are inactive areas and the white portions are active areas. 
OSD menus can be displayed on those unused black areas.
1.Auto: Scales an image proportionally to fit the 
projectors native resolution in its horizontal width. 
This is suitable for the incoming image which is 
neither in 4:3 nor 16:9 and you want to make most 
use of the screen without altering the images aspect 
ratio.
2.
Real: The image is projected as its original 
resolution, and resized to fit within the display area. 
For input signals with lower resolutions, the 
projected image will display smaller than if resized 
to full screen. You could move the projector 
towards the screen to increase the image size if 
necessary. You may also need to refocus the 
projector after making these adjustments.
3.4:3: Scales an image so that it is displayed in the 
center of the screen with a 4:3 aspect ratio. This is 
most suitable for 4:3 images like computer 
monitors, standard definition TV and 4:3 aspect 
DVD movies, as it displays them without aspect 
alteration.

							Operation 324.16:9: Scales an image so that it is displayed in the 
center of the screen with a 16:9 aspect ratio. This is 
most suitable for images which are already in a 16:9 
aspect, like high definition TV, as it displays them 
without aspect alteration.

Adjusting Color
Highlight Color in the PICTURE menu and adjust the values by pressing  / on the 
projector or remote control.
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
Highlight Tint in the PICTURE menu and adjust the values by pressing  / on the 
projector or remote control.
The higher the value, the more reddish the picture becomes. The lower the value, the more 
greenish the picture becomes.
Adjusting Sharpness

projector or remote control.
The higher the value, the sharper the picture becomes. The lower the value, the softer the 
picture becomes.
Adjusting Brilliant Color
Highlight Brilliant Color in the PICTURE menu and select by pressing  / on the 
projector or remote control.
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.
On is the default and recommended selection for this projector. When Off is selected, the 
Color Temperature function is not available.
Selecting a Color Temperature
Highlight Color Temperature in the PICTURE menu and adjust the values by pressing  /
 on the projector or remote control.
The options available for color temperature* settings vary according to the signal type 
selected.
1.T1: With the highest color temperature, T1 makes the image appear the most bluish 
white than other settings.
2.T2: Makes images appear bluish white.
3.T3: Maintains normal colorings for white.
4.T4: 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.
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. 
Downloaded From projector-manual.com BenQ Manuals 
						

							Operation 35 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, 
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 
p ro j e c to r,  h ow e ve r,  yo u r  p ro j e c to r  s u p p l i e r  s hould 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 any image 
from the disc on the screen and enter the 3D Color Management menu to make 
adjustments.
To adjust the settings:
1. Go to the PICTURE menu and highlight 3D Color Management.
2. Press Mode/Enter and the 3D Color Management page displays.
3. Highlight Primary Color and press  /  to select a color from among Red, Yellow, 
Green, Cyan, Blue, or Magenta.
4. 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.
5. 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.
6. 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. 
7. Repeat steps 3 to 6 for other color adjustments.
8. Make sure you have made all of the desired adjustments.
9. Press Menu/Exit to exit and save the settings.
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.
