Benq MW767 Manuel D’Utilisation
Positioning your projector
20
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.
