Formulas
Units: Inches (for millimeters multiply final number by 25.4)
D = Screen Diagonal (4:3)
H = D x 0.8 H = Screen Width (4:3)
V = D x 0.6 V = Screen Height (4:3)
M 1.38889H M = Projection magnification
B = 0.2165M B = Vertical distance between lens center and screen center
C (Wide) = 1.4483M – 2.165 C = Throw distance
C (Tele) = C (Wide) x 1.15
D = 0.0535M D = Vertical distance between lens center and top of screen (bottom of screen
for desktop application)
