11Step 1: Installing the Projector
Connections and Preparations
When using the 16:9 aspect ratio screen
Unit: mm (inches)
To calculate the installation measurements (SS: Screen Size)
a (minimum) = {(SS × 21.27/0.7227) – 35.160899} × 1.025
b (maximum) = {(SS × 33.9409273/0.7227) – 37.678872} × 0.975
c = (SS/0.7227 × 9)
d = (SS/0.7227 × 8)
e = (SS/0.7227 × 4.5)
When using the 4:3 aspect ratio screen
Unit: mm (inches)
To calculate the installation measurements (SS: Screen Size)
a (minimum) = {(SS × 21.27/0.5906) – 35.160899} × 1.025
b (maximum) = {(SS × 33.9409273/0.5906) – 37.678872} × 0.975
c = (SS/0.5906 × 9)
d = (SS/0.5906 × 8)
e = (SS/0.5906 × 4.5)
