- projector - ceiling
- projector - screen
To find this correct position for the projector, equipped with HD145
lenses, formulas are given in the next paragraph.
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.
