BenQ MS502, MX503 Obtaining a preferred projected image size, Projection dimensions, Screen 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.

For example, if you are using an 120-inch screen, the recommended projection distance is 4755 mm and the vertical offset is 183 mm.

If your measured projection distance is 6.0 m (6000 mm), the closest match in the "Distance from screen (mm)" column is 5943 mm. Looking across this row shows that a 150'' (about 3.8 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.
