each factors in the projected image size.
For example, if you are using an 120-inch screen, the recommended projection distance is
715 mm and the vertical offset is 320 mm.
715 mm and the vertical offset is 320 mm.
If your measured projection distance is 0.9 m (900 mm), the closest match in the
column is 902 mm. Looking across this row shows that a 150'' (about

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.
