BenQ MX731 User Manual page 15

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.

For example, if you are using a 120-inch screen, the recommended projection distance is 3520 mm.
If your measured projection distance is 5000 mm, the closest match in the
column is 4987 mm. Looking across this row shows that a 170'' (about 4.3 m) screen is required.
To optimize your projection quality, we suggest you do the projection within non-gray area.
