For example, If you are using a 60-inch screen, the projection distance is 2194 mm and
with a vertical offset of 120 mm.
If your measured projection distance is 5.5 m (5500 mm), the closest match in the
"Distance from screen (mm)"
150'' (about 3810 mm) 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.
