Notes                                                                     

 

For screen sizes not indicated on the projection tables, use the formulas below. 

 

If the figures on the tables do not match the results of formulas, use the figures in the table. 

 

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%.
