Positioning your projector
15
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
Refer to
"Dimensions" on page 57
for the center of lens dimensions of this projector
before calculating the appropriate position.
The screen aspect ratio is 4:3 and the projected picture is 4:3
For example, if you are using an 120-inch screen, the recommended projection distance is
4755 mm and the vertical offset is 183 mm.
If your measured projection distance is 6.0 m (6000 mm), the closest match in the
"Projection distance (mm)"
column is 5943 mm. Looking across this row shows that a 150''
(about 3.8 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.
