For example, if you are using an 120-inch screen, the recommended projection distance is 2063 mm and the vertical offset is 40 mm.

If your measured projection distance is 3.0 m (3000 mm), the closest match in the "Distance from screen (mm)" column is 3094 mm. Looking across this row shows that a 180'' (about 4.6 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.
