Aspect Ratio
The native display resolution of this projector is in a 16:9 aspect ratio. However, you 
may use this function to display projected picture of different aspect ratio. 
In the following illustrations, the black portions are inactive areas and the 
white portions are active areas.
• Auto
Scales a picture proportionally to fit the projectors 
native resolution in its horizontal or vertical width. 
This makes the most use of the screen and maintains 
the aspect ratio of a picture.
• 4:3
Scales the picture so that it is displayed in the center 
of the screen with a 4:3 aspect ratio. 
• 
16:9 
Scales a picture so that it is displayed in the center 
of the screen with a 16:9 aspect ratio. 
• Wide
Stretches a picture in a horizontal direction to fit 
the screen width. It does not alter the height of a 
picture. 
• Letter Box
Scales a picture to fit the projector’s native 
resolution in its horizontal width and resizes the 
picture height to the 3/4 of the projection width. 
This makes a picture greater than the screen height. 
The top and bottom edges of the displayed picture 
are cropped. This suits the contents which are 
produced in letter box format (with black bars on 
the top and bottom).
Image Position
Displays the Image Position window. You may use the directional arrow keys on the 
projector or remote control to adjust the position of the projected picture. 
The values shown on the lower position of the window change with every key press 
you made.
This function is only available when the PC signal is selected.
Overscan 
Adjustment
Conceals the poor picture quality in the four edges. 
The greater the value, the more portion of the picture is concealed while the screen 
remains filled and geometrically accurate. Setting 0 means the picture is 100% 
displayed.

3D
This projector supports playing three-dimensional (3D) content transferred through 
your 3D-compatible video devices and contents, such as PlayStation consoles (with 
3D game discs), 3D Blu-ray 3D players (with 3D Blu-ray discs), 3D TV (with 3D 
channel), and so on. After you have connected the 3D video devices to the projector, 
wear the BenQ 3D glasses and make sure the power is on to view 3D contents.
When watching 3D contents, 
• the image may seem misplaced, however, this is not a product malfunction.
• take appropriate breaks when watching 3D content.
• stop watching 3D content if you feel fatigue or discomfort.
• keep a distance from the screen of about three times the effective height of 
the screen when watching 3D content.
• children and people with a history of oversensitivity to light, heart problems, 
or have any other existing medical condition should be refrained from 
watching 3D content.  
The following functions help enhance your 3D viewing experience.
• 3D Mode
The default setting is Auto and the projector automatically chooses an appropriate 
3D format when detecting 3D contents. If the projector cannot recognize the 3D 
format, manually choose a 3D mode according to your preference.
When this function is enabled:
• the brightness level of the projected image decreases.
• the Picture Mode cannot be adjusted.
• the 2D Keystone can only be adjusted within limited degrees.
• 3D Sync Invert
When your 3D image is distorted, enable this function to switch between the image 
for the left eye and the right eye for the more comfortable 3D viewing experience.
These functions are accessible through the remote control.

High Altitude Mode
It is a mode for operation in areas like high altitude or high temperature. 
Activate the function when your environment is between 1500 m –3000 m 
above sea level and ambient temperature is between 0°C–30°C.
Do not use this function if your altitude is between 0 m and 1500 m and 
ambient temperature is between 0°C and 35°C. If you turn on the mode 
under such a condition, the projector will be over cooled.
Operation under High Altitude Mode may cause a higher decibel operating 
noise level because of increased fan speed necessary to improve overall system 
cooling and performance.
If you use this projector under other extreme conditions 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 High 
Altitude Mode to solve these symptoms. However, this is not to state that 
this projector can operate under any and all harsh or extreme conditions.

Maintenance
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. 
Never remove any parts of the projector except the lamp. Contact your dealer or local customer service 
center if the projector fails to operate as expected.
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface. 
Before cleaning any part of the projector, turn it off using the proper shutdown procedure (see Shutting 
down the projector), unplug the power cable, and let it cool down completely. 
•  Use a canister of compressed air to remove dust. 
•  If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner and gently 
wipe the lens surface.
•  Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or volatile solvent, such as 
alcohol, benzene, thinner or insecticide. Using such materials or maintaining prolonged contact with 
rubber or vinyl materials may result in damage to the projector surface and cabinet material.
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 while the projector is switched on or is still hot from previous use.
Cleaning the projector case
Before cleaning any part of the projector, turn it off using the proper shutdown procedure (see Shutting 
down the projector), unplug the power cable, and let it cool down completely. 
•  To remove dirt or dust, wipe the case with a soft, dry, lint-free cloth.
•  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
To store the projector for an extended time:
•  Make sure the temperature and humidity of the storage area are within the recommended range for 
the projector. Refer to Specifications or consult your dealer about the range.
•  Retract the adjuster feet.
•  Remove the batteries from the remote control.
•  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.
