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: 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 α (tele) = tan

Screen Formulas (4:3): H = V x 4/3 V = H x 3/4 Screen Diagonal = H x 5/4
