Both 4:3 and 16:9 screens are fully supported with proper aspect ratio control for both type sources using NEC developed 
scaling technology. Menu selections have settings for each screen type and aspect ratio control for each source type. 

 

• 

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

• 

The ceiling must be strong enough to support the projector and the installation must be in accordance with any local 
 building codes. 

• 

Distances are in inches, for millimeters multiply by 25.4. 

• 

Distances may vary 

±5%. 

 

The Projection Formulas use the image width for calculation. Image width is the same for all aspect ratios, only vertical image size 
varies. For proper projector placement, determine the image width for a desired screen size. Use the Screen Formulas below to 
calculate all screen dimensions. Plug in the image width for “W” in the Projection Formulas. 
Refer to the diagrams and charts for popular screen sizes on page 2 and 3.
