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 16:9 screens:
Projection Formulas:
NP01FL: C = 0.7426W – 1.33
NP02ZL: C(Wide) = 1.0885W – 1.798 ------ C(Tele) = 1.4225W – 1.795
Standard: C(Wide) = 1.3743W – 2.022 ------ C(Tele) = 1.8319W – 2.015
NP03ZL: C(Wide) = 1.7992W – 2.830 ------ C(Tele) = 2.8325W – 2.840
NP04ZL: C(Wide) = 2.7275W – 4.830 ------ C(Tele) = 4.3620W – 4.850
NP05ZL: C(Wide) = 4.3259W – 7.625 ------ C(Tele) = 6.5228W – 7.645
Note: Tilting the front of the projector or down by more than 45° from level could reduce lamp life by up to 20%.
