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.

Refer to "Dimensions" on page 75 for the center of lens dimensions of this projector before calculating the appropriate position.

For example, if you are using a 120-inch screen, the recommended projection distance is 4457 mm and the vertical offset is 91 mm - 274 mm.

If your measured projection distance is 5.0 m (5000 mm), the closest match in the "Distance from screen (mm)" column is 4457 mm or 5571 mm. Looking across this row shows that a 120'' (about 3.0 m) or 150'' (about 3.8 m) screen is required.

There is 3% tolerance among these numbers 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, 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.
