Remote control effective range
Infra-Red (IR) remote control sensors are located on the front and the 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).
Make sure that there are no obstacles between the remote control and the IR sensors on the 
projector that might obstruct the...

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.
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).
The modern digital...

How to determine the recommended screen size for a 
given distance
This method can be used for situations where you have purchased this projector and would 
like to know what screen size will fit in your room.
The maximum screen size is limited by the physical space available in your room. 
1. Determine the aspect ratio of the screen you need, 16:9 or 4:3? If you need a 16:9 
screen, refer to Table A1
 (page 17) or Table A2 (page 18). If you need a 4:3 screen, refer 
to...

Table B2: The screen aspect ratio is 4:3 and the projected picture is 16:10
There is 3% tolerance among these numbers in Table A1, Table A2, Table B1, and Table B2 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,...
