Positioning your projector
Choosing a location
Your projector is designed to be installed in one of four possible installation locations: 
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.1. Front Table
Select this location with the projector 
placed on a table in front of the screen. 
This is the most common way to position 
the projector for quick setup and 
portability.2. Rear Table
Select this location with the projector 
placed on a table behind the screen.
Note that a special rear projection screen 
is required.
*Set Rear Table in the SYSTEM 
SETUP: Basic > Projector Installation 
menu after you turn the projector on.
3. 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 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.
*Set Rear Ceiling in the SYSTEM 
SETUP: Basic > Projector Installation 
menu after you turn the projector on.

							Positioning your projector 20
There is 5% 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 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.
