When using the 16:9 aspect ratio screen
Unit: mm (inches)
To calculate the installation measurements (SS: Screen Size)
a (minimum) = {(SS Ч 21.27/0.7227) – 35.160899} Ч 1.025 + 123.5
a (maximum) = {(SS Ч 33.9409273/0.7227) – 37.678872} Ч 0.975 + 123.5
x (minimum) = (SS/0.7227 × 4.5)
x (maximum) = b + (SS/0.7227 × 9) + 75
