§For Screen Sizes of 60 to 300 inches not indicated on the projection tables, use the formulas below.
§Set the projection distance based on the width of the screen.
§If the figures on the tables do not match the figures in the formulas, use the figures in the table.
Formulas
Units: Inches Units: Millimeters
M= 1.25 x W / 33.02 M= 1.25 x W / 1.3
A= C / COSINE αA= C / COSINE α
B= (8 x M) + 5.598 B= (8 x M) + 142.2
C(Zoom Wide) = (53.2 x M) - 3.37 C(Zoom Wide) = (53.2 x M) - 85.609
C(Zoom Telephoto) = C (Zoom Wide) x 1.3055 C(Zoom Telephoto) = C (Zoom Wide) x 1.3055
D= (3 x W / 8) - E D= 25.4 x (3 x W / 8) - E
E= (8 x M) + 3.433 E= (8 x M) + 87.2
αα = TAN -1 ((E - 3.433) / C) αα = TAN -1 ((E - 87.2) / C)
W = Width of Screen
A= Distance between lens center and screen center
B= Vertical distance between top of NEC ceiling mount and screen center
C= Horizontal throw distance between screen surface and projector lens
D= Vertical distance between projector base and screen bottom
E= Vertical distance between desk top level and screen center
