Positioning your projector18
Table C: The screen aspect ratio is 16:10 and the projected picture is 16:10
For example, if you are using a 120-inch, 4:3-aspect-ratio screen and the projected picture is
16:10, please refer to Table B2
on page 17, the recommended projection distance is 1192 mm
and the vertical offset is 76 mm.
If you need a 16:9 screen to project a 16:9 picture and your measured projection distance is
1.5 m (1500 mm), please refer to Table A1
on page 16. The closest match in the "(b) Distance
from screen" column is 1623 mm. Looking across this row shows that a 150'' (about 3.8 m)
screen is required.
There is 3% tolerance among these numbers due to optical component variations.
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.
