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.
•
Distances are in inches, for millimeters multiply by 25.4.
•
Distances may vary
±
5%.
