Obtaining a preferred projected image size The distance from the projector lens to the screen, the zoom setting (if available), and the video format each factors in the projected image size.

If your measured projection distance is 6200 mm, the closest match in the "Projection distance (mm)" column is 6264 mm. Looking across this row shows that a 150'' (about 3.8 m) screen is required. To optimize your projection quality, we suggest to do the projection within non-gray area. 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. Positioning your projector 15
