  Using the projector
EnglishYou can change the projected image ratio (no matter what aspect the source is) by using the Aspect buttons on 
the remote control or in the Display > Aspect Ratio OSD menu. Select an aspect ratio to suit the format of the 
video signal and your display requirements. There are five aspect ratios available:
In the pictures below, the black portions are inactive areas and the white portions are active areas.
The Anamorphic setting stretches and resizes linearly, except that it treats the vertical and horizontal 
dimensions independently. It stretches the height of the source image until it reaches the full projected height, 
and stretches the width of the source image until it reaches the full projected width. This may alter the projected 
aspect, depending upon the original aspect of the source image. Anamorphic is most suitable for images which 
are already in a 16:9 aspect, like high definition TV, as it displays them without aspect alteration.
The 4:3 setting is most suitable for 4:3 images like standard definition TV and 4:3 aspect DVD movies, as it 
displays them without aspect alteration. 
The Letterbox setting resizes an image proportionately both vertically and horizontally from the width of a 4:3 
aspect to the width of a 16:9 aspect and centers it onscreen. This produces an image greater in height than can 
be displayed, so part of the image is lost (not displayed) along the top and bottom edges of the projection. This 
is suitable for the display of movies which are presented in letterbox format (with black bars top and bottom. 
The Wide setting stretches the image horizontally in a non-linear manner, that is, the edges of the image are 
stretched more than the centre of the image, to prevent distortion of the central part of the image. This is 
suitable for occasions where you want to stretch the width of a 4:3 aspect image to the width of a 16:9 aspect 
screen. It does not alter the height. Some widescreen movies have been produced with their width squashed 
down to the width of a 4:3 aspect, and are best viewed when restretched back to their original width using the 
Wide setting. 
The Real setting displays the image in a one-to-one pixel mapping without alteration or resize in the centre of 
the projection. This is most suitable for use with PC and RGBHD source inputs. 
3. Adjusting contrast ratio
The contrast ratio is the measurement of the difference between the brightest whites and the darkest blacks a 
display can show. A projector with larger contrast ratio is able to show more subtle color details and allow 
extraneous room light. The projector is with very high contrast ratio. You are able to tune a suitable contrast 
ratio according to your room light and preference. To manually adjust the contrast ratio, press the IRIS button 
on the remote control. When the button is pressed, an adjustment bar   
displays on the screen. To lower the contrast and increase brightness, press the e button on the remote control 
or in the Advanced --> Advanced - 30 step IRIS menu. To raise the contrast and decrease brightness, press the 
f button on the remote control or in the Advanced --> Advanced - 30 step IRIS menu. The L and H on the 
adjustment bar’s both sides represent the contrast ratio Low or High. There are 30 phases from Low to High 
available for adjustments.1.Anamorphic: Scales an image 
so that it is displayed in the 
center of the screen with a 
16:9 aspect ratio.
2.4:3: Scales an image so that it 
is displayed in the center of 
the screen with a 4:3 aspect 
ratio.
3.Letterbox: Enlarges an image 
with letterbox format to 
display it in full-screen format 
with a 16:9 aspect ratio. The 
upper and lower portions of 
the image are cropped.4.Wide: A 4:3 aspect ratio image is enlarged 
NON-linearly in horizontal direction to 
accommodate 16:9 full-screen display. This 
stretches only the right and left sides of the 
image; the central part is unchanged.
5.Real: One-to-one mapping is performed on the 
input signal without any scaling with the image 
displayed at the center of the screen.

This menu contains items necessary for basic image setup.
1.Language: Sets the language for the OSD menus.
2.Mirror: The projector can be installed on a ceiling or behind a screen, or with one or more mirrors. There 
are four settings for choice. Contact your dealer for the ceiling mount bracket if you need to install the 
projector on a ceiling. See page 14 for more information.
3.High Altitude: This item is designed for those who use the projector in extreme environments, like high 
temperature or high altitude. We recommend you select Ye s when your environment is higher than 3000 
feet, or is hotter than 40°C. 
Operation with Ye s selected may caused a higher decibel operating noise level because of increased fan 
speed necessary to improve over-all cooling system and performance.
If you use the projector under other extreme environments excluding the above, it may display auto shut-
down symptoms, which is designed to protect your projector from over-heating. In cases like this, you 
should switch to Yes to solve these symptoms. However, this is not to state that this projector can operate 
under any and all harsh and extreme environments.
4.Black Level: 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 which 
use PAL equipment or Japanese NTSC standard, the grayscale is measured from 0 IRE (black) to 100 IRE 
(white). We suggest that you check the input source if it is with 0 IRE or 7.5 IRE, then select accordingly.
5.Ke ystone: Corrects for trapezoidal distortion resulting from the angle of projection. It can provide 
correction of up to ± 12 degrees.
6.Pattern: It will be displayed with the aspect ratio setting made using the Aspect Ratio function of the 
DISPLAY menu. Use this pattern when installing the projector, even if there is no input signal. Use it to 
adjust the image size and the focus.

							30 Additional information  
EnglishAdditional information
Care of the projector
Your projector needs little maintenance. The only thing you have to do on a regular basis is keep the lens clean 
and clean or replace the air filter. Never remove any parts of the projector except the lamp or the air filter. 
Contact your dealer or local BenQ Customer Service Centre if the projector fails to operate as expected.
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface. Before you attempt to clean the lens, turn the 
projector off, unplug the power cable, and leave it several minutes to cool completely.
1. Use a canister of compressed air to remove dust. (Available from building hardware or photographic 
suppliers.)
2. If there is stubborn dirt or smudge marks, use a proper photographic lens brush or moisten a clean soft lens 
cloth with lens cleaner to gently wipe the lens surface.
Never touch the lens with your finger or rub the lens with abrasive materials. Even paper towels can 
damage the lens coating. Only ever use a proper photographic lens brush, cloth, and cleaning solution. Do 
not attempt to clean the lens whilst the projector is switched on or is still hot from previous use.
Cleaning the projector case
Before you attempt to clean the case, turn the projector off, unplug the power cable, and leave it several minutes 
to cool completely.
1. To remove dirt or dust, wipe the case with a soft, dry, lint-free cloth.
2. To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral detergent. Then wipe the case.
Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the case.
Storing the projector
If you need to store the projector for an extended time, please:
1. Make sure the temperature and humidity of the storage area are within the recommended range for the 
projector. Please refer to the Spec. page in this manual or consult your dealer about the range.
2. Retract the adjuster feet.
3. Remove the batteries from the remote control.
4. Pack the projector in its original packing or equivalent.
Transporting the projector
It is recommended that you ship the projector with its original packing or equivalent. When you carry the 
projector yourself, please use a soft carry case.
Cleaning and replacing the dust filter
It is necessary to clean the dust filter periodically every 1000 hours use. You can use the menu Setup> Dust Filter 
Hours to check how long the filter has been used. If the filter is not cleaned, it can become clogged with dust and 
prevent proper ventilation. This can cause overheating and a malfunction of the projector.
Should the projector filter become seriously clogged with 
dust, it and cause over-heating inside of the projector. You 
will see the message pictured to the right before the projector 
shuts down and powers off. 
Please install a new filter.
The projector will turn off in 1 min.
