4. In some countries, the line voltage is
NOT stable. This projector is
designed to operate safely within a
mains voltage between 100 to 240
volts AC, but could fail if power cuts
or surges of 10 volts occur. In
areas where the mains voltage
may fluctuate or cut out, it is
recommended that you connect
your projector through a power
stabilizer, surge protector or
uninterruptible power supply
(UPS).

Ceiling mounting the projector
We want you to have a pleasant
experience using your BenQ projector,
so we need to bring this safety matter
to your attention to prevent possible
damage to person and property.
If you intend to mount your projector
on the ceiling, we strongly recommend
that you use a proper fitting BenQ
projector ceiling mount kit and that
you ensure it is securely and safely
installed.
If you use a non-BenQ brand projector
ceiling mount kit, there is a safety risk
that the projector may fall from the
ceiling due to an improper attachment
through the use of the wrong gauge or
length screws.
You can purchase a BenQ projector
ceiling mount kit from the place you
purchased your BenQ projector. BenQ
recommends that you also purchase a
separate Kensington lock compatible
security cable and attach it securely to
both the Kensington lock slot on the
projector and the base of the ceiling
mount bracket. This will perform the
secondary role of restraining the
projector should its attachment to the
mounting bracket become loose.

The screen aspect ratio is 16:10 and the projected picture is in a 16:10 aspect ratio
For example, if you are using an 120-inch screen, the recommended projection distance is
630 mm and the vertical offset is 380 mm.
If your measured projection distance is 0.3 m (300 mm), the closest match in the "(b)
Distance from screen" column is 308 mm. Looking across this row shows that a 80'' (about
2.0 m) screen is required.
All measurements are approximate and may vary from the actual sizes.
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.

Connection 17
Connection
When connecting a signal source to the projector, be sure to:
1. Turn all equipment off before making any connections.
2. Use the correct signal cables for each source.
3. Ensure the cables are firmly inserted.
• In the connections shown below, some cables may not be included with the projector (see "Shipping
contents" on page 8). They are commercially available from electronics stores.
• The connection illustrations below are for reference only. The rear connecting jacks available on the
projector vary with each projector model.
• Many notebooks do not turn on their external video ports when connected to a projector. Usually a key
combo like FN + F3 or CRT/LCD key turns the external display on/off. Locate a function key labeled CRT/
LCD or a function key with a monitor symbol on the notebook. Press FN and the labeled function key
simultaneously. Refer to your notebook's documentation to find your notebook's key combination.
• The D-Sub output only works when an appropriate D-Sub input is made to the PC IN-1 jack.

• If you wish to use this connection method when the projector is in standby mode, make sure the
Monitor Out function is turned on in the SYSTEM SETUP: Advanced menu. See "Standby Settings"
on page 48 for details.
Connecting video source devices
You need only connect the projector to a video source device using just one of the
connecting methods, however each provides a different level of video quality. The method
you choose will most likely depend upon the availability of matching terminals on both the
projector and the video source device as described below:
Connecting audio
The projector has built-in speaker(s) which are designed to provide basic audio
functionality accompanying data presentations for business purposes only. They are not
designed for, nor intended for stereo audio reproduction use as might be expected in
home theater or home cinema applications.
The built-in speaker(s) will be muted when the AUDIO-OUT jack is connected.
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is connected. See
"Connecting audio" on page 18 for details.
• If the selected video image is not displayed after the projector is turned on and the correct video source
has been selected, check that the video source device is turned on and operating correctly. Also check
that the signal cables have been connected correctly.
Playing sound through the projector
You can make use of the projector (mixed mono) speaker(s) in your presentations, and
also connect separate amplified speakers to the AUDIO OUT socket of the projector.
If you have a separate sound system, you will most likely want to connect the audio output
of your Video source device to that sound system, instead of to the mono audio projector.
You can also use a microphone to output the sound through the projector speaker(s).
Once connected, the audio can be controlled by the projector On-Screen Display (OSD)
menus. See "Audio Settings" on page 47 for details.

Connection 19
The table below describes the connection methods for different devices, and where the
sound is from.
About the microphone input
• If you wish to use a microphone, connect a 3.5 mini jack cable microphone to the
projector.
• You can use a wireless microphone as long as a wireless module is attached to the
projector’s microphone input jack and it works well with the associated devices. To
ensure a quality use of the wireless microphone, it is recommended that your
microphone conforms to the specifications listed in the table below.
• To adjust microphone volumes
• Directly set microphone volume levels in the SYSTEM SETUP: Advanced
> Audio Settings > Microphone Volume menu.
• To make the microphone input available when the projector is in standby mode, turn
on the SYSTEM SETUP: Advanced > Standby Settings > Microphone menu.
• If the microphone is not working, check the volume setting and cable connection.
• You might get feedback noise from the microphone when you are too close to the
speaker(s) of the projector. Move the microphone away from the speaker(s) of the
projector. The greater volume you require, the greater distance you need to be away
from the speaker(s) to prevent the noise.

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 projector's native resolution
in its horizontal or vertical 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 image's
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 adjust the zoom setting or
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 some
computer monitors, standard
definition TV and 4:3 aspect DVD
movies, as it displays them without
aspect alteration.
4. 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.
5. 16:10: Scales an image so that it is
displayed in the center of the screen
with a 16:10 aspect ratio. This is most
suitable for images which are already
in a 16:10 aspect, as it displays them
without aspect alteration.

The higher the value, the more greenish the picture becomes. The lower the value, the
more reddish the picture becomes.
Adjusting Sharpness
The higher the value, the sharper the picture becomes. The lower the value, the softer the
picture becomes.
Adjusting Brilliant Color
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.

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 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 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.
2. Press MODE/ENTER on the projector or remote control 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.
Operation32
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.
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.
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.
