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 |
