Screen/Aspect
Ratio
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.
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.
•
All calculations are based on 4:3 aspect ratio.
•
Distances are in inches, for millimeters multiply by 25.4.
•
Distances may vary
±5%.
Formulas
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:

NP03ZL: C(Wide) = 2.0069W – 2.830 ------ C(Tele) = 3.1710W – 2.840
NP04ZL: C(Wide) = 3.0537W – 4.830 ------ C(Tele) = 4.8860W – 4.850
4:3 Screen Formulas: 16:9 Screen Formulas:
NP05ZL: C(Wide) = 4.8275W – 7.625 ------ C(Tele) = 7.3379W – 7.645
W = H x 4/3
W = H x 16/9
H = W x 3/4
H = W x 9/16
