Obtaining a preferred image size

the video format each factors in the projected image size.

For example, if you are using a 120-inch screen, the recommended
projection distance is 3200 mm.
If your measured projection distance is 2660 mm, the projected screen
size is 100-inch.
Note
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.
