							Introduction 11
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.
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 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. 
						

							Introduction 14Infra-Red (IR) remote control sensor is located on the front of the projector. The remote 
control must be held at an angle within 22.5 degrees perpendicular to the projectors IR 
remote control sensor to function correctly. The distance between the remote control and 
the sensor should not exceed 8 meters (~ 26 feet).
Make sure that there are no obstacles between the remote control and the IR sensor on the 
projector that might obstruct the infra-red beam.
Replacing the remote control battery
1. To open the battery cover, turn the remote control over to view its back, push on the 
finger grip on the cover and slide it up in the direction of the arrow as illustrated. The 
cover will slide off.
2. Remove any existing batteries (if necessary) and install two AAA batteries observing 
the battery polarities as indicated in the base of the battery compartment. Positive (+) 
goes to positive and negative (-) goes to negative.
3. Refit the cover by aligning it with the base and sliding it back down into position. Stop 
when it clicks into place.
• Avoid excessive heat and humidity. 
• There may be battery damage if the battery is incorrectly replaced. 
• Replace only with the same or equivalent type recommended by the battery manufacturer.
• Dispose of the used battery according to the battery 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. • Operating the projector from the front• Operating the projector from the rear

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.
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. 
						

							Positioning your projector 16
Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting (if available), and the 
video format each factors in the projected image size.
16:9 is the native aspect ratio of this projector.
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). 
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 18, 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 proportional to 
the projection distance.
BenQ has provided a table of 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).4:3 aspect image in a 16:9

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 18 and find the closest match to your screen size in the left 
columns labelled Screen size. 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 (mm) 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 4710 mm 
and with a vertical offset of 513 mm.
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 18 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 size 
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 (mm) 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 4.0 m (4000 mm), the closest match 
in the Average column is 3920 mm. Looking across this row shows that a 100-inch screen is 
required.
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 details.

Projection dimensions
Refer to Dimensions on page 82 for the center of lens dimensions of this projector before 
calculating the appropriate position.
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 projectors optical characteristics. This will help you 
determine the exact mounting position so that it best suits your installation location.
