the oor in front of the screen. This is the most
common way to position the projector for quick
setup and portability.
3.Front Ceiling
Select this location with the projector suspended
upside-down from the ceiling in front of the
screen.
Purchase the BenQ Projector Ceiling Mounting Kit
from your dealer to mount your projector on the
ceiling.
* Set Front Ceiling in the SYSTEM SETUP:
Basic > Projector Installation menu after you
turn the projector on.
2.Rear Table
Select this location with the projector placed near
the oor behind the screen.
Note that a special rear projection screen is
required.
* Set Rear Table in the SYSTEM SETUP:
Basic > Projector Installation menu after you
turn the projector on.
4.Rear Ceiling
Select this location with the projector suspended
upside-down from the ceiling behind the screen.
Note that a special rear projection screen and the
BenQ Projector Ceiling Mounting Kit are required
for this installation location.
* Set Rear Ceiling in the SYSTEM SETUP:
Basic > Projector Installation menu after you
turn the projector on.
Your room layout or personal preference will dictate which installation location you select. Take into
consideration the size and position of your screen, the location of a suitable power outlet, as well as the
location and distance between the projector and the rest of your equipment.

Note:
A 5-percent tolerance exists between these numbers due to the difference among optical components. BenQ recommends that
if you intend to permanently install the projector, you should physically test the projection size and distance using the actual
projector in situ before you permanently install it, so as to make allowance for this projector's optical characteristics. This will
help you determine the exact mounting position so that it best suits your installation location. To optimize the projection quality,
we suggest to project images in an area without grayscale.

Connection
Before connection
y Please read the manual for connection to external devices carefully before connection.
y Shut down the power supply of all devices before connecting the cable.
y Bear the following in mind before connecting the cable. A breakdown might occur if not following
these rules.
y Please touch metal objects nearby to release static electricity before connecting the cable to the
projector or device linking to the projector.
y Do not use any over-length cable to connect to the projector or use it to connect the device
to the projector. A long cable would operate like an antenna. It is more likely to be interfered by
noise.
y When connecting a cable, connect the GND (earth) part rst and then insert the connector
linking to the device.
y Get a connecting cable not provided by the supplier to connect the external device to the system.
y If there is too much jitter in the video signal, the image on the screen shakes. Therefore, you must
connect the time base corrector (TBC).
y If the synchronous signal output in the computer or video device is cut off due to the change of the
video output setting or other reasons, the color of projected image would be distorted for a short
time.
English
y The projector receives the video signal, Y/C signal, YCBCR/YPBPR signal, simulated RGB signal (TTL
level for synchronous signal) and numeric signal.
y Some computer models are not compatible with the projector.
y Use the cable compensator when using the long cable to connect the device to the projector. The
image might not be displayed properly if not using the cable compensator.

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.
Only in permanent installations with controlled lighting levels such as boardrooms, lecture theaters, or
home theaters, should color management be considered. Color management provides ne 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 projector, however, your projector
supplier should 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.

magenta.
5. Press ▼ to highlight Saturation and adjust its values to
your preference by pressing ◄/►. Every adjustment made
will reect 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.
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.
