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

Introduction 11
Positioning your projector
Choosing a location
Your projector is designed to be installed in one of four possible installation locations:
1. Table in front of screen;
2. Ceiling in front of screen;
3. Table at rear of screen;
4. Ceiling at rear of screen.
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 in the Advanced > Mirror 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 in the Advanced > Mirror 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 in the Advanced > Mirror 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.
Positioning your projector12
Safety instructions for ceiling mounting of 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
prgc61 4.23(o)4.1hevc61n.1649-g(g)-t.1(v9)h.1(c)1 s.3(r4Bc.1he)-6.29t tr4B.
Positioning your projector 13
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 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 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 projec tor. 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 16, that this type of projection causes the bottom edge
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).

display area
Positioning your projector14
How to determine the position of the projector for a given screen size
1. Select your screen size.
2. Refer to the table and find the closest match to your screen size in the left columns
labelled ' 4:3 Screen Di agonal '. Using this va lue, lo ok across thi s row to t he rig ht to fi nd
the corresponding average distance from screen value in the column labelled 'Average'.
This is the projection distance.
3. On that s ame row, l ook acr oss to t he rig ht colu mn and m ake not e of the vertical Off set
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 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 4467 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 ima ge distortion
will occur. Use the Keystone function to correct the distortion. See "Correcting keystone" on
page 29 for details.
How to determine the recommended screen size for a given distance
This method can be use d 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 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
diagonal listed in that row. That is the projected image size of the projector at that
projection distance.
4. On that s ame row, l ook acr oss to t he rig ht colu mn and m ake not e of the vertical Off set
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 4593 mm. Looking across this row shows that a 3000 mm (3 m)
screen is required. If you can only obtain imperial sized screens, the listed screen sizes on
either side of the 3 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 need to be reduced to fit the 9' size screen, or
increased to 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.
