1. Important safety instructions
Your BenQ projector is designed and tested to meet the latest standards for safety of
information technology equipment. However, to ensure safe use of this product, it is
important that you follow the instructions mentioned in this manual and marked on the
product.
Safety Instructions
1. Please read this manual before you
operate your projector. Save it for
future reference.
2. Do not look straight at the projector
lens during operation. The intense
light beam may damage your eyes.
4. Always open the lens shutter or
remove the lens cap when the
projector lamp is on.
5. 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).
3. Refer servicing to qualified service
personnel.
6. Do not block the projection lens with
any objects when the projector is
under operation as this could cause
the objects to become heated and
deformed or even cause a fire. To
temporarily turn off the lamp, press
BLANK on the projector or remote
control.
Important safety instructions 5
Safety Instructions (Continued)
7. The lamp becomes extremely hot
during operation. Allow the projector
to cool for approximately 45 minutes
prior to removing the lamp assembly
for replacement.
8. Do not operate lamps beyond the
rated lamp life. Excessive operation of
lamps beyond the rated life could
cause them to break on rare occasions.
10. Do not place this product on an
unstable cart, stand, or table. The
product may fall, sustaining serious
damage.
11. Do not attempt to disassemble this
projector. There are dangerous high
voltages inside which may cause death
if you should come into contact with
live parts. The only user serviceable
part is the lamp which has its own
removable cover.
Under no circumstances should you
ever undo or remove any other covers.
Refer servicing only to suitably
qualified professional service
personnel.
9. Never replace the lamp assembly or
any electronic components unless the
projector is unplugged.
6 Important safety instructions
12. When the projector is under
operation, you may sense some heated
air and odor from its ventilation grill.
It is a normal phenomenon and not a
product defect.
Safety Instructions (Continued)
13. Do not place this projector in any of
the following environments.
- Space that is poorly ventilated or
confined. Allow at least 50 cm clearance
from walls and free flow of air around the
projector.
- Locations where temperatures may
become excessively high, such as the
inside of a car with all windows rolled up.
- Locations where excessive humidity, dust,
or cigarette smoke may contaminate
optical components, shortening the
projector's life span and darkening the
picture.
14. Do not block the ventilation holes.
- Do not place this projector on a blanket,
bedding or any other soft surface.
- Do not cover this projector with a cloth
or any other item.
- Do not place inflammables near the
projector.
If the ventilation holes are seriously
obstructed, overheating inside the
projector may result in a fire.
15. Always place the projector on a level,
horizontal surface during operation.
- Do not use if tilted at an angle of more
than 40 degrees left to right, nor at angle
of more than 35 degrees front to back.
Using the projector when it is not fully
horizontal may cause a malfunction of,
or damage to, the lamp.

is securely installed.
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 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.

Operating the LASER pointer
The LASER Pointer is a
presentation aid for
professionals. It emits red
colored light when you press it
and the indicator lights up red.
The laser beam is visible. It is
necessary to press and hold
LASER for continuous output.
Do not look into the laser light window or
shine the laser light beam on yourself or
others. See the warning messages on the
back of the remote control and the
enclosed ''User Information'' prior to using
it.
The laser pointer is not a toy. Parents should be
mindful of the dangers of laser energy and keep
this remote control out of the reach of children.
Making the remote control a wired
control
The remote control is equipped with a jack on
the top allowing connection to the projector
with a 2.5mm mini jack cable available in the
market. This helps you easily locate the remote
control when needed as it is connected to the
projector and within the distance no greater
than the cable’s length.
Introduction 15
Remote control effective range
Infra-Red (IR) remote control sensors are
located on the front and the back of the
projector. The remote control must be held at
an angle within 30 degrees perpendicular to
the projector's IR remote control sensors to
function correctly. The distance between the
remote control and the sensors should not
exceed 6 meters (~ 20 feet).
Make sure that there are no obstacles between
the remote control and the IR sensors on the
projector that might obstruct the infra-red
beam.

when it clicks into place.
Avoid leaving the remote control and batteries
in an excessive heat or humid environment like
the kitchen, bathroom, sauna, sunroom or in a
closed car.
Replace only with the same or equivalent type
recommended by the battery manufacturer.
Dispose of the used batteries according to the
manufacturer's instructions and local
environment regulations for your region.
Never throw the batteries into a fire. There may
be danger of an explosion.
If the batteries are dead or if you will not be
using the remote control for an extended
period of time, remove the batteries to avoid
damage to the remote control from possible
battery leakage.
16 Introduction
3. Positioning your projector
Choosing a location
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.
The projector is designed to be installed in one of four possible installation locations.
1. Floor Front
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. Ceiling Front
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 Ceiling Front after you turn the
projector on.
3. Ceiling Rear
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 Ceiling Rear after you turn the
projector on.
4. Floor Rear
Select this location with the projector placed
near the floor behind the screen.
Note that a special rear projection screen is
required.
*Set Floor Rear after you turn the projector
on.
*To set the projector position:
1. Press MENU on the projector or remote control and
then press / until the System Setup menu is
highlighted.
2. Press / to highlight Projector Position and press
/ until the correct position is selected.

Positioning your projector 17
Obtaining a preferred projected picture size
The distance from the projector lens to the screen, the zoom setting, and the video format,
each factors in the projected picture size.
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 picture 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.
You can see from the diagram on page 20, that this type of projection causes the bottom edge
of the projected picture to be vertically offset from the horizontal plane of the projector.
When ceiling mounted, this refers to the top edge of the projected picture.
If the projector is positioned further away from the screen, the projected picture 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 picture size and the vertical offset dimension, which are directly
proportional to the projection distance.
BenQ has provided tables of 16:9-aspect-ratio and 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. Determine the aspect ratio of your screen, 16:9 or 4:3? If you have a 16:9 screen, refer
to Table A
projected picture aspect ratio you’ve got.
2. Select a screen size you desire.
3. Refer to the table and find the closest match to your screen size in the left columns
labelled "Screen Dimensions". Using this value, look across this row to the right to find
the corresponding average distance from screen value in the column labelled
"Average". This is the projection distance.
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.
18 Positioning your projector
. If you have a 4:3 screen, refer to Table B1 or Table B2 depending on the
5. 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 3
above, and offset by the value determined in step 4 above.
For example, if you are using an 120-inch, 4:3-aspect-ratio screen and the projected picture
is 15:9, please refer to Table B2
vertical offset of 146 mm.
. The average projection distance is 4133.7 mm and with a
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. Determine the aspect ratio of the screen you need, 16:9 or 4:3? If you need a 16:9
screen, refer to Table A
depending on the projected picture aspect ratio you’ve got.
2. Measure the distance between the projector and where you want to position the
screen. This is the projection distance.
3. Refer to that table and find the closest match to your measurement in the average
distance from screen column labelled "Average". Check that your measured distance is
between the min and max distances listed on either side of the average distance value.
4. Using this value, look across that row to the left to find the corresponding "Screen
Dimensions" listed in that row. That is the recommended screen size you can purchase
at that projection distance.
5. 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.
For example, if you need a 16:9 screen to project a 16:9 picture and your measured
projection distance was 4.8 m (4800 mm), please refer to Table A
"Average" column is
required.
. If you need a 4:3 screen, refer to Table B1 or Table B2
. The closest match in the
4508 mm. Looking across this row shows that a 120'' (3.0 m) screen is

There is 3% tolerance among these numbers in Table A, Table B1, and Table B2 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.

If you place the projector in a different position (to that recommended), you will have to tilt
it down or up, or even turn it slightly left or right to center the picture on the screen. In these
situations, some picture distortion will occur. To correct the distortion, see "Correcting
picture distortion" on page 37 for details.

4. 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 10). They are commercially available from electronics stores.
Connecting a computer
The projector provides VGA and DVI input sockets that allow you to connect it to both
IBM® compatibles and Macintosh® computers. A Mac adapter (an optional accessory) is
needed if you are connecting legacy version Macintosh computers.
To connect the projector to a notebook or desktop computer (either through a VGA
cable or VGA to DVI-A cable):
•With a VGA cable: •With a VGA to DVI-A cable:
1. Take the supplied VGA cable and
connect one end to the D-Sub output
socket of the computer.
2. Connect the other end of the VGA
cable to the D-SUB IN signal input
socket on the projector.
3. If you wish to use the remote paging function (see "Remote paging operations" on
page 56), take a USB cable and connect the larger end to the USB port of the
computer, and the smaller end to the USB socket on the projector.
The final connection path should be like that shown in the following diagram:
1. Take a VGA to DVI-A cable and
connect the VGA end to the D-Sub
output socket of the computer.
2. Connect the DVI end of the VGA to
DVI-A cable to the DVI-I signal input
socket on the projector.

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.

Connecting a monitor
If you want to view your presentation close-up on a monitor as well as on the screen, you
can connect the projector to an external monitor by following the instructions below.
To connect the projector to a monitor (either through a VGA cable or VGA to
DVI-A cable):
• With a VGA cable: • With a VGA to DVI-A cable:
Note: Your monitor must be equipped with a
DVI input socket.
1. Connect the projector to a computer as described in "Connecting a computer" on
page 23.
The D-SUB OUT output only works when an appropriate D-Sub input is made to the
projector. Be sure the projector is connecting with the computer using the D-SUB IN
socket, not the DVI-I socket.
2. Take a suitable VGA cable (only one
supplied) and connect one end of the
cable to the D-Sub input socket of the
video monitor.
3. Connect the other end of the cable to
the D-SUB OUT socket on the
projector.
The final connection path should be like that shown in the following diagram:
