Notes

§ For Screen Sizes of 40 to 200 inches not indicated on the projection tables, use the formulas below.

§ If the figures on the tables do not match the results of formulas, use the figures in the table.

§ The ceiling must be strong enough to support the LCD projector and the installation must be in accordance with any local

building codes.

• All calculations are based on 4:3 aspect ratio.

• Distances are in inches, for millimeters multiply by 25.4.

• Distances may vary ±5%.

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 = 0.96212H M = Projection magnification

B = 0.3346M B = Vertical distance between lens center and screen center

C (Wide) = 1.3623M – 2.325 C = Throw distance

C (Tele) = 1.6756M – 2.325

D = 0.0585M D = Vertical distance between lens center and top of screen (bottom of screen

for desktop application)

α (wide) = tan

-1

(B/C(wide)) α = Throw angle

α (tele) = tan

-1

(B/C(tele))
