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 of
the projector’s IR remote control
sensors to function correctly. The
distance between the remote control
30 degrees
6 meters
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.
Installing or replacing the remote control battery
1. Pull out the battery holder.
2. Insert the new battery in the holder.
Note that the positive polarity should
face outward.
3. Push the holder into the remote
control.
• Avoid excessive heat and humidity.
• There may be danger of damage to the remote and injury to those nearby if the battery is
incorrectly replaced.
• Replace only with the same or equivalent type recommended by the manufacturer.
• Dispose of the used battery according to the manufacturer’s instructions.
• Never throw a battery into a fire. There may be danger of an explosion.
• If the battery is dead or if you will not be using the remote control for a long time, remove the
battery to prevent damage to the remote control from possible battery leakage.
Introduction 11
Positioning your projector
Choosing a location
Your projector is designed to be installed in one of two possible installation locations:
1. Floor in front of screen; or
2. Floor at rear of screen
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.
I. 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.
II. 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 in the Advance > Mirror menu
after you turn the projector on.
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.
The maximum (native) resolution of the projector is 1024 x 768 pixels, which is a 4 to 3
aspect ratio (expressed as 4:3). 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.
4:3 aspect image in a 4:3 aspect 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 centre 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
Positioning your projector12
16:9 aspect image scaled to a 4:3 aspect dis-
play area
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 centre 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).
You can see from the diagram on page 15, that this type of projection causes the bottom edge
of the projected image to be vertically offset from the horizontal plane of the projector. 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 (see "Screen size chart" on page
15) to assist you in determining the ideal location for your projector. There are two
dimensions to consider, the perpendicular horizontal distance from the centre 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. Select your screen size.
2. Refer to the table on page 15 and find the closest match to your screen size in the left
columns labelled '4:3 Screen Diagonal' and '4:3 Aspect in mm'. 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.
3. 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.
4. The recommended position for the projector is aligned perpendicular to the
horizontal centre 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 4757 mm
and with a vertical offset of 229 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 24 for keystone correction.
Positioning your projector 13
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. Measure the distance between the projector and where you want to position the
screen. This is the projection distance.
2. Refer to the table on page 15 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.
3. Using this value, look across that row to the left to find the corresponding screen
diameter listed in that row. That is the projected image size of the projector at that
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 placement of the screen in relation to the
horizontal plane of the projector.
For example, if your measured projection distance was 4.5m (4500mm), the closest match in
the Average column is 4682mm. Looking across this row shows that a 3000mm (3m) screen
is required. If you can only obtain imperial sized screens, the listed screen sizes on either side
of the 3m screen are the 9' and 10' screens.
Checking the min and max projection distance values for the these (9' & 10') sizes, indicates
that the 4.5m measured projection distance will fit these screens too. The projector can be
adjusted (using the zoom control) to display on these different screen sizes at that projection
distance. Be aware that these different screens have different vertical offset values.

Connection
When connecting a signal source to the projector, be sure to:
• Turn all equipment off before making any connections.
• Use the correct signal cables for each source.
• 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 6). They are commercially available from electronics stores.
• This projector has no speaker or built-in support for audio reproduction.
Connecting a computer
The projector provides a VGA input socket that allows you to connect it to a notebook or
desktop computer.
Additionally, you can also connect the projector to a computer via the USB cable so you can
perform paging operations of the application on the PC or notebook. (see "Remote paging
operations" on page 26).
To connect the projector to a notebook or desktop computer:
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/COMP IN signal input socket
on the projector.
3. If you wish to use the remote paging function (see "Remote paging operations" on
page 26), take the supplied 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:
USB cable
Notebook or desktop computer
• A Mac adapter (an optional accessory) is needed if you are connecting legacy version (http:/
/www.info.apple.com/usen/legacy/) Macintosh computers.
• Many notebook computers 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 computer. Press FN and the labeled function key simultaneously. Refer to your
notebook computer’s documentation to find your notebook computer ’s key combination.

VGA cable
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:
•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 Component Video (not to be confused with
composite Video). Digital TV tuner and DVD players output Component Video natively, so
if available on your devices, this should be your connection method of choice in preference
to (composite) Video.
See "Connecting a Component Video source device" on page 18 for how to connect the
projector to a component video device.
Better video quality
The S-Video method provides a better quality analog video than standard composite Video.
If you have both composite Video and S-Video output terminals on your Video source
device, you should elect to use the S-Video option.
See "Connecting an S-Video source device" on page 19 for how to connect the projector to
an S-Video device.
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
described here.
See "Connecting a composite Video source device" on page 20 for how to connect the
projector to a composite Video device.
Connection 17
Connecting a Component Video source device
Examine your Video source device to determine if it has a set of unused Component Video
output sockets 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.
To connect the projector to a Component Video source device
1. Take the (optional accessory) Component Video to VGA (D-Sub) adaptor cable and
connect the end with 3 RCA type connectors to the Component Video output sockets
of the Video source device. Match the color of the plugs to the color of the sockets;
green to green, blue to blue, and red to red.
2. Connect the other end of the Component Video to VGA (D-Sub) adaptor cable (with
a D-Sub type connector) to the D-SUB/COMP IN socket on the projector.
The final connection path should be like that shown in the following diagram:
Component Video to VGA
(D-Sub) adaptor cable

Component Video is the only video output that delivers native 16:9 aspect ratio picture.
If you connect the projector to a High Definition TV (HDTV) tuner, the following standards
are supported:
• 480i • 480p
• 576i • 576p
• 720p (50/ 60 Hz) • 1080i (50/ 60 Hz)
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.
Connection18
Connecting an S-Video source device
Examine your Video source device to determine if it has an unused S-Video 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.
To connect the projector to an S-Video source device
1. Take an appropriate S-Video cable (not supplied) and connect one end to the S-Video
output socket of the Video source device.
2. Connect the other end of the S-Video cable to the S-VIDEO socket on the projector.

Calculation of lamp hour
When the projector is in operation, the duration (by 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 = hours used in Economic mode + hours used in normal
See "Economic Mode (Off)" on page 35 for more information on Economic mode.
The lamp hour in Economic mode is calculated as 2/3 of that in normal mode. That is, using
the projector in Economic mode helps to extend the lamp hour by 1/3.
