15 Positioning your projector
Positioning your projector
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.
Projection dimensions
• The screen aspect ratio is 16:9 and the projected picture is in a 16:9 aspect ratio
For example, if you are using a 100-inch screen, the recommended projection distance is
269 mm.
If your measured projection distance is 230 mm, the closest match in the "Projection
distance (mm)" column is 214 mm. Looking across this row shows that a 90'' (about 2.3
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. The distance between the ambient light reflection
screen and the projector should also be considered during installation.
