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.
18. Do not place liquids near or on the
projector. Liquids spilled into the
projector may cause it to fail. If the
projector does become wet, disconnect
it from the power supply's wall socket
and call BenQ to have the projector
serviced.
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.
19. This product is capable of displaying
inverted images for ceiling mount
installation.
Use only BenQ's Ceiling Mount Kit for
mounting the projector and ensure it is
securely installed.

Positioning your projector
Choosing a location
Your projector is designed to be installed in one of four possible installation locations:
1.
Front Table
Select this location with the projector placed near the
floor in front of the screen. This is the most common
way to position the projector for quick setup and
portability.
2.
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 Position menu after you turn the projector
on.
3.
Rear Table
Select this location with the projector placed near the
floor behind the screen.
Note that a special rear projection screen is required.
Set Rear Table in the SYSTEM SETUP: Basic >
Projector Position 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 Position 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.

Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, and the video format
each factors in the projected image size.
4:3 is the native aspect ratio of this projector. To be able to project a complete 16:9
(widescreen) aspect ratio image, the projector can resize and scale a widescreen image to the
projector's native aspect width. This will result in a proportionally smaller height equivalent
to 75% of the projector's native aspect height.
16:9 aspect image scaled to a 4:3 aspect
4:3 aspect image in a 4:3 aspect display area
display area
Thus, a 16:9 aspect image will not utilize 25% of the height of a 4:3 aspect image displayed
by this projector. This will be seen as darkened (unlit) bars along the top and bottom
(vertical 12.5% height respectively) of the 4:3 projection display area whenever displaying a
scaled 16:9 aspect image in the vertical center of the 4:3 projection display area.
When determining the position of your projector, you should consider its intended use and
input signal aspect ratios. All inputs (other than composite Video being fed a 16:9 aspect
signal) will display in a 4:3 aspect ratio (and will require an additional 33% display height
than that of the scaled 16:9 aspect image projection area).
IMPORTANT: Do not select a permanent projector position based upon a 16:9 projection if you
will ever need to select an input (other than composite Video being fed a 16:9 aspect signal).
The projector should always be placed horizontally level (like flat on a table), and positioned
directly perpendicular (90° right-angle square) to the horizontal center of the screen. This
prevents image distortion caused by angled projections (or projecting onto angled surfaces).
The modern digital projector does not project directly forward (like older style reel-to-reel
film projectors did). Instead, digital projectors are designed to project at a slightly upward
angle above the horizontal plane of the projector. This is so that they can be readily placed
on a table and will project forward and upwards onto a screen positioned so that the bottom
edge of the screen is above the level of the table (and everyone in the room can see the
screen).
If the projector is mounted on a ceiling, it must be mounted upside-down so that it projects
at a slightly downward angle.
of the projected image to be vertically offset from the horizontal plane of the projector.
When ceiling mounted, this refers to the top edge of the projected image.
If the projector is positioned further away from the screen, the projected image size
increases, and the vertical offset also increases proportionately.
When determining the position of the screen and projector, you will need to account for
both the projected image size and the vertical offset dimension, which are directly
proportional to the projection distance.
BenQ has provided a table of 4:3-aspect-ratio screen sizes to assist you in determining the
ideal location for your projector. There are two dimensions to consider, the perpendicular
horizontal distance from the center of the screen (projection distance), and the vertical
offset height of the projector from the horizontal edge of the screen (offset).

How to determine the position of the projector for a given
screen size
1.
2.
Select your screen size.
Refer to the table and find the closest match to your screen size in the left columns
the corresponding average distance from screen value in the column labelled
"Average". This is the projection distance.
3.
4.
On that same row, look across to the right column and make note of the Vertical offset
value. This will determine the final vertical offset placement of the projector in
relation to the edge of the screen.
The recommended position for the projector is aligned perpendicular to the
horizontal center of the screen, at the distance from the screen determined in step 2
above, and offset by the value determined in step 3 above.
For example, if you are using a 120 inch screen, the average projection distance is 4667 mm
and with a vertical offset of 183 mm.
If you place the projector in a different position (to that recommended), you will have to tilt
it down or up to center the image on the screen. In these situations, some image distortion
will occur. Use the Keystone function to correct the distortion. See "Correcting keystone" on
page 33 for details.
How to determine the recommended screen size for a
given distance
This method can be used for situations where you have purchased this projector and would
like to know what screen size will fit in your room.
The maximum screen size is limited by the physical space available in your room.
1.
2.
Measure the distance between the projector and where you want to position the
screen. This is the projection distance.
Refer to the table and find the closest match to your measurement in the average
between the min and max distances listed on either side of the average distance value.
Using this value, look across that row to the left to find the corresponding screen
diagonal listed in that row. That is the projected image size of the projector at that
projection distance.
On that same row, look across to the right column and make note of the Vertical offset
value. This will determine the final placement of the screen in relation to the
horizontal plane of the projector.
3.
4.
For example, if your measured projection distance was 4.5m (4500mm), the closest match in
the Average column is 4593 mm. Looking across this row shows that a 3000 mm (3.0 m)
screen is required. If you can only obtain imperial sized screens, the listed screen sizes on
either side of the 3.0 m screen are the 9' and 10' screens.
Checking the min and max projection distance values for these screen sizes, indicates that
the 4.5 m measured projection distance will fit the 10' size screen. The projector can be
adjusted (using the zoom control) to display on these different screen sizes at those
projection distances. Be aware that these different screens have different vertical offset
values.

There is 3% tolerance among these numbers due to optical component variations. 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.

Connecting Video source devices
This section describes how to connect the projector to Video source devices using video
cables. Video cable connections are recommended for Video presentations.
You can connect your projector to various Video source devices that provide any one of the
following output sockets:
•
•
•
•
DVI
Component Video
S-Video
Video (composite)
You need only connect the projector to a Video source device using just one of the above
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:
Best video quality
The best available video connection method is DVI. If your source device is equipped with a
DVI socket, based on the type of DVI connector you have, you can enjoy digital or high-end
analog video quality.

If no DVI source is available, the next best video signal is Component Video (not to be
confused with composite Video). Digital TV tuners and DVD players output Component
Video natively, so if available on your devices, they should be your connection method of
choice in preference to S-Video or (composite) Video.

Least video quality
Composite Video is an analog video and will result in a perfectly acceptable, but less than
optimal result from your projector, being the least video quality of the available methods

Connecting Audio
The projector has a built-in mono speaker which is designed to provide basic audio
functionality accompanying data presentations for business purposes only. It is not designed
for, nor intended for stereo audio reproduction use as might be expected in home theatre or
home cinema applications. Any stereo audio input (if provided), is mixed into a common
mono audio output through the projector speaker.

Connecting a DVI source device
The projector provides a DVI input socket that allows you to connect it to a DVI source
device like a DVD player, or a VGA output device like a notebook or desktop computer.
There are three types of DVI connectors: DVI-A, DVI-D, and DVI-I. The DVI-I socket is an
integrated connector which supports both formats: DVI-A, and DVI-D.
DVI-A format is used to carry a DVI signal to an analog (VGA) display, or vice-versa.
Although some signal quality is lost from the signal conversion, it still transmits higher
picture quality than a standard VGA connection.
DVI-D format is used to directly carry a digital signal to a digital display without signal
conversion. The pure digital connection provides faster and higher image quality than an
analog connection, due to the nature of the digital format.
DVI-A and DVI-D formats are non-interchangeable. You cannot connect a DVI-A format
connector to DVI-D equipment and visa-versa. Make sure you know which kind of format
your equipment is fitted with before you purchase any cables. Or you can purchase a DVI-I
cable which will be more useful in any type of DVI connection situation.
Examine your source device to determine if it has an unused DVI output socket available:

•
If so, you can continue with this procedure.
If not, you will need to reassess which method you can use to connect to the device.

Selecting the aspect ratio
The 'aspect ratio' is the ratio of the image width to the image height. Most analog TV and
computers are in 4:3 ratio, and digital TV and DVDs are usually in 16:9 ratio.
With the advent of digital signal processing, digital display devices like this projector can
dynamically stretch and scale the image output to a different aspect than that of the image
input source.

About the aspect ratio
In the pictures below, the black portions are inactive areas and the white portions are active
areas.
1.
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
computer monitors, standard definition TV and 4:3 aspect DVD
movies, as it displays them without aspect alteration.
2.
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.
16:9 aspect ratio is only sourced through the Component Video input when
being fed an appropriate 16:9 aspect signal. See "Connecting a Component
image size" on page 15 for details.
3.
Auto: Scales an image proportionally to fit the projector's native
resolution in its horizontal width. This is suitable for the incoming
image which is either in 4:3 nor 16:9 and you want to make most use
of the screen without altering the image's aspect ratio.

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.

*About color temperatures:
There are many different shades that are considered to be "white" for various purposes. One
of the common methods of representing white color is known as the “color temperature”. A
white color with a low color temperature appears to be reddish white. A white color with a
high color temperature appears to have more blue in it.

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:

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.

Lamp information
Getting to know the lamp hour
When the projector is in operation, the duration (in hours) of lamp usage is automatically
calculated by the built-in timer. The method of calculating the equivalent lamp hour is as
follows:
Total (equivalent) lamp hour
= 1 (hours used in Economic mode) + 4/3 (hours used in normal mode)
The lamp hour in Economic mode is calculated as 3/4 of that in normal mode. That is, using
the projector in Economic mode helps to extend the lamp hour by 1/3.
To obtain the lamp hour information:
1.
Press MENU/EXIT and then press
is highlighted.
/
until the SYSTEM SETUP: Advanced menu
2.
Press to highlight Lamp Settings and press Mode/enter. The Lamp Settings page
displays.
4.
5.
You will see the Equivalent Lamp Hour information displaying on the menu.
To leave the menu, press MENU/EXIT.
You can also get the lamp hour information on the INFORMATION menu.

via the OSD menu.
•
Setting Lamp Mode as Economic
Using Economic mode reduces system noise and power consumption by 20%. If the
Economic mode is selected, the light output will be reduced and result in darker projected
pictures.
Setting the projector in Economic mode also extends the lamp operation life. To set
Economic mode, go into the SYSTEM SETUP: Advanced > Lamp Settings > Lamp Mode
menu and press
/
.
•
Setting Auto Power Off
This function allows the projector to turn off automatically if no input source is detected
after a set period of time to prevent unnecessary waste of lamp life.
To set Auto Power Off, go into the SYSTEM SETUP: Basic > Auto Power Off menu and
press
/
. The time period can be set from 5 to 30 minutes in 5-minute increments. If the
preset time lengths are not suitable for your presentation, select Disable. The projector will
