For example, if you are using a 120-inch, 4:3-aspect-ratio screen and the projected picture is 16:10, please refer to Table B2 on page 17, the recommended projection distance is 1192 mm and the vertical offset is 76 mm.

If you need a 16:9 screen to project a 16:9 picture and your measured projection distance is

1.5m (1500 mm), please refer to Table A1 on page 16. The closest match in the "(b) Distance from screen" column is 1623 mm. Looking across this row shows that a 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.
