Obtaining a preferred projected image size

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.

If you need a 4:3 screen to project a 4:3 picture and your measured projection distance is 4000 mm, please refer to Table A1 on page 16. The closest match in the "Distance from screen (mm)" column is 4246 mm. Looking across this row shows that a 120'' (about 3.0 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.
