Obtaining A Preferred Projected Image Size - BenQ ES500 User Manual

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 66
before calculating the appropriate position.

For example, if you are using a 120-inch screen, the average projection distance is 5040
mm and with a vertical offset of 274 mm.
If your measured projection distance is 5.0 m (5000 mm), the closest match in the
"Projection distance (mm)"
(about 3.0 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.
