Remote control effective range
Infra-Red (IR) remote control sensors are located on the front and back of the projector. The 
remote control must be held at an angle within 30 degrees perpendicular to the projectors 
IR remote control sensors to function correctly. The distance between the remote control 
and the sensors should not exceed 8 meters (~ 26 feet).

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.

Positioning your projector 14
Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, and the video format 
each factors in the projected image size.
For example, if you are using a 120-inch, 4:3-aspect-ratio screen and the projected picture is 
16:10, please refer to Table B2
 on page 16, the recommended projection distance is 1192 mm 
and the vertical offset is 76 mm.
If you need a 16:9 screen to project a 16:9 picture and your measured...

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...
