* Where to install the projector?
Abbreviations used on drawing and diagrams on next pages
B = Distance between ceiling and top of the screen.
A = Correction Value, extra value to be added to B to obtain the correct
installation position. (In some cases the A value can be negative.)
CD = Total distance between projector and ceiling.
CD = A + B (When the result is negative, enlarge the distance between
ceiling and top of the screen, mount screen lower, until CD becomes
zero or positive)
SW = Screen width.
PD = Perpendicular distance between screen and projector.
Formulas for Projector to screen distance and correction value A with regard to the
screen width for HD145 lenses (metric).
Formulas (metric)
PD[m] = 1.21 x SW[m] + 0.213
A[cm] = 12.95 x SW[m] - 22.83
Formulas for Projector to screen distance and correction value A with regard to the
screen width for HD145 lenses (inch).
Formulas (inch)
PD = 1.21 x SW + 8.39
A = 0.1295 x SW - 8.99
