 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)

Definitions:

H = Horizontal Screen Width (4:3)
V = Vertical Screen Height (4:3)

B = Vertical distance between lens center and screen center
C = Throw distance
D = Vertical distance between lens center and screen top (screen bottom for desktop application)
α = Throw Angle

Projection Formulas:

B = 0.3193H H = Screen Diagonal x 4/5

C (wide) = 1.2996H – 2.325 V = Screen Diagonal x 3/5

C (tele) = 1.5985H – 2.325 Screen Diagonal = H x 5/4

D = 0.0557H

α (wide) = tan

α (tele) = tan
