Projection dimensions
Refer to "Dimensions" on page 71 for the center of lens dimensions of this projector
before calculating the appropriate position.
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)" column is 5485 mm. Looking across this row shows that a
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.
