Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting (if available), and the content
format each factors in the projected image size.
Projection dimensions

For example, if you are using a 120-inch screen, the recommended projection distance is 1487 mm.
If your measured projection distance is 1000 mm, the closest match in the
column is 992 mm. Looking across this row shows that a 80'' (about 2.0 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
projector's optical characteristics. This will help you determine the exact mounting position so that it best suits your
installation location.
Mounting the projector
If you intend to mount your projector, we strongly recommend that you use a proper fitting BenQ
projector mounting 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
down due to an improper attachment through the use of the wrong gauge or length screws.
Before mounting the projector
• Purchase a BenQ projector mounting 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.
