Positioning your projector
Choosing a location
Your projector is designed to be installed in one of four possible installation locations:
1.
2.
3.
4.
Floor in front of screen;
Ceiling in front of screen;
Floor at rear of screen;
Ceiling 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.
If you use the projector with wireless function, there's no need to worry about data cable
connections.This gives you the flexibility to site the projector anywhere in the room up to a
range of 20m away from your notebook, and switch between presentations on different
notebooks instantly without fiddling with cables
To use the wireless function, you need to install a BenQ wireless module to the projector and
enable your notebook/desktop PC with wireless connection. For more information, refer to

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.
16:9 aspect image scaled to a 4:3 aspect dis-
4:3 aspect image in a 4:3 aspect display area
play 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
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).
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 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.
2.
Select your screen size.
Refer to the table and find the closest match to your screen size in the left columns
labelled 'Screen Diameter' 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.
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 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 4691 mm
and with a vertical offset of 46 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 28 for keystone correction.
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
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.
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.
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 4617mm. 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 these screen 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.

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

projector to a composite Video device.
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.
If you wish, you can make use of the projector (mixed mono) speaker in your presentations,
and also connect separate amplified speakers to the Audio Out socket of the projector. The
audio output is a mixed mono signal and controlled by the projector Volume and Mute
settings.
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.

Lamp information
Calculation of 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 = hours used in Economic mode + 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 1/4.
Warning message
When the Lamp indicator lights up red or a message appears suggesting it is time to replace
the lamp, please install a new lamp or consult your dealer. An old lamp may cause a
malfunction in the projector and in some instances the lamp may explode.
For more detailed information on projector warnings, please refer to "Indicators" on page
47.
The Lamp indicator light and Temperature warning light will light up if the lamp becomes too
hot. Turn the power off and let the projector cool for 45 minutes. If the Lamp or Temp indicator
still lights up after turning the power back on, please contact your dealer.
The following Lamp warning displays will remind you to change the lamp.

The lamp has been in operation for 2950 hours. A
new lamp should be fitted to avoid the
inconvenience of shutdown when the projector runs
out of lamp time.
The lamp has been in operation for over 3000 hours.
This message will flash in the center of the screen for
about 30 seconds together with the Lamp indicator
lighting up red for 40 seconds.
If this warning message displays, the projector will
shutdown in 40 seconds. The lamp MUST be
replaced before the projector will operate normally.

Safety instructions for ceiling mounting of your BenQ
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.
