Positioning your projector20
MX822ST
For example, if you are using a 120-inch screen, the average projection distance is 1.53 m
and with a vertical offset of
27 cm.
If your measured projection distance is 2.0 m (200 cm), the closest match in the "Distance
from screen (m)" column is
1.91 m. Looking across this row shows that a 150'' (about 4.0
m) 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.
