Notes
 For screen sizes not indicated on the projection charts, use the formulas below.
 If a value in a chart does not match the results of the formulas, use the values in the chart.
 The ceiling must be strong enough to support the projector and the installation must be in accordance with any local
building codes.
 All formulas are based on a 4:3 aspect ratio and screen.
 4:3 sources can be displayed on a 16:9 screen without vertical “squeezing”, see “Aspect Ratio” in the user manual.
 Distances are in inches, for millimeters multiply by 25.4.
 Distances may vary ±5%.
Formulas (for a 4:3 screen)
units: inches (for millimeters multiply final number by 25.4)
Calculate projection values by plugging the screen width (H) into the projection formulas.
Projection Formulas: Definitions:
B= 0.3023H H= Horizontal Screen Width (4:3)
C(wide) = 1.5165H – 1.357 V= Vertical Screen Height (4:3)
C(tele) = 1.8197H – 1.629 B= Vertical distance between lens center and screen center
D= 0.0727H C= Throw distance
α(wide) = tan-1 (B/C(wide)) α= Throw Angle
α(tele) = tan-1 (B/C(tele))
Screen Formulas (4:3):
H= V x 4/3
V= H x 3/4
Screen Diagonal = H x 5/4
