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...

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...

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)....

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....

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...
