Formulas
Units: Inches
M = 1.25 x W / 33.02 A = C / COSINE B = (8 x M) + 5.598 C (Zoom Wide) = (53.2 x M) - 3.37 C (Zoom Telephoto) = C (Zoom Wide) x 1.3055 D = (3 x W / 8) - E E = (8 x M) + 3.433 = TAN
-1
Units: Millimeters
M = 1.25 x W / 1.3 A = C / COSINE B = (8 x M) + 142.2 C (Zoom Wide) = (53.2 x M) - 85.609 C (Zoom Telephoto) = C (Zoom Wide) x 1.3055 D = 25.4 x (3 x W / 8) - E E = (8 x M) + 87.2 = TAN -1 ((E - 87.2) / C)
((E - 3.433) / 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
