							Introduction 13
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 or wall, we strongly recommend 
that you use a proper fitting BenQ projector ceiling mount kit or wall mount kit and 
that you ensure it is securely and safely installed.
If you use a non-BenQ brand projector mounting kit, there is a safety risk that the 
projector may fall from the ceiling or wall due to an improper attachment through 
the use of the wrong gauge or length screws.
You can purchase a BenQ projector ceiling mount or wall 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 mounting 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 16Infra-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 projector's 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 comparent. 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.
SetFront Ceiling in the SYSTEM SETUP: Basic > 
Projector Installation 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.
SetRear Table in the SYSTEM SETUP: Basic > 
Projector Installation 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.
SetRear Ceiling in the SYSTEM SETUP: Basic > 
Projector Installation menu after you turn the projector on. 
						

							Positioning your projector 18
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.
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 19, 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).

Projection dimensions
Refer to "Dimensions" on page 97 for the center of lens dimensions of this projector 
before calculating the appropriate position.
MX766
MW767
For example, If you are using the MX766 and a 150-inch screen, the projection distance is 
7.14 m and with a vertical offset of 34.3 m.
If you are using the MX766 and your measured projection distance is 4.0 m (4000 mm), the 
closest match in the "Distance from screen (m)" column is 3.79 m. Looking across this row 
showsthat a 80'' (about 2.0 m) screen is required.

MX822ST
For example, if you are using a 120-inch screen, the average projection distance is 1.53 m 
and with a vertical offset of 
27 cm. 
If your measured projection distance is 2.0 m (200 cm), the closest match in the "Distance 
from screen (m)" column is 
1.91 m. Looking across this row shows that a 150'' (about 4.0 
m) screen is required.
All measurements are approximate and may vary from the actual sizes.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.
