Screen/Aspect Ratio
16:10, 16:9 and 4:3 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 calculati ons 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 height is the same for all aspect ratios, only horizontal image
size varies when using a 16:10 aspect ratio screen. 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 “W” for a 16:10 aspect ratio image
in the Projection Formulas.
Refer to the diagrams (page 5) and charts below for popular screen sizes 16:10 screens:
Projection Formulas: Definitions:
NP01FL: C = 0.8260W – 1.33 W = Image Width
NP02ZL: C(Wide) = 1.2120W – 1.798 ------ C(Tele) = 1.5770W – 1.795 H = Image Height (size)
Standard: C(Wide) = 1.5330W – 2.022 ------ C(Tele) = 2.0390W – 2.015 C = Throw distance
NP03ZL: C(Wide) = 1.9910W – 2.830 ------ C(Tele) = 3.1460W – 2.840
NP04ZL: C(Wide) = 3.0300W – 4.830 ------ C(Tele) = 4.8465W – 4.850 16:10 Screen Formulas:
NP05ZL: C(Wide) = 4.7888W – 7.625 ------ C(Tele) = 7.2779W – 7.645 W = H x 16/10
H = W x 10/16
Screen Diagonal = W x 18.868/16
Note: Tilting the front of the projector or down by more than 45° from level could reduce lamp life by up to 20%.
