Positioning your projector 17
Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting (if available), and
the video format each factors in the projected image size.
Projection dimensions
Refer to "Dimensions" on page 68 for the center of lens dimensions of this projector
before calculating the appropriate position.
The screen aspect ratio is 16:9 and the projected picture is 16:9
For example, if using a 120-inch screen, the average projection distance is 4069 mm and
with a vertical offset of 105 mm.
If your measured projection distance is 5.0 m (5000 mm), the closest match in the
"Projection distance (mm)" column is 5100 mm. Looking across this row shows that a 150''
(about 4.0 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.
