Formulas: 4:3 Aspect Ratio (PA500X/PA600X—XGA)
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:
Projection Formulas:
NP11FL: C = 0.827W – 1.374
NP12ZL: C(Wide) = 1.214W – 1.794 ------ C(Tele) = 1.578W – 1.794
NP13ZL: C(Wide) = 1.524W – 1.974 ------ C(Tele) = 3.043W – 1.972
NP14ZL: C(Wide) = 3.034W – 4.844 ------ C(Tele) = 4.855W – 4.844
NP15ZL: C(Wide) = 4.797W – 7.630 ------ C(Tele) = 7.291W – 7.630
Note: Tilting the front of the projector up or down by more than 45° from level could reduce lamp life by up to 20%.
