Aspect RatioThe 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 PositionDisplays 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 
AdjustmentConceals 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.

3DThis 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 Sync Mode
Select DLP-Link or 3D VESA for DLP-Link or 3D VESA glasses.
•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 Depth Adjust
Adjusts the depth level of 3D images on the screen to let you perceive more 
natural and comfortable effect of 3D contents.
•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.
The function is accessible through the remote control.

							Menu Functions 55 High Altitude ModeIt 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 the High Altitude Mode if your altitude is between 0 m and 1500 
m and temperature is between 0°C and 30°C. The projector will be over 
cooled, if you turn the mode on under such a condition.
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.

security for the projector. See Utilizing the password function on page 40 for

ISFThe ISF calibration menu is password protected and only accessible by authorized 
ISF calibrators. The ISF (Imaging Science Foundation) has developed carefully 
crafted, industry-recognized standards for optimal video performance and has 
implemented a training program for technicians and installers to use these 
standards to obtain optimal picture quality from BenQ video display devices. 
Accordingly, we recommend that setup and calibration be performed by an ISF 
certified installation technician.
