Formulas: 16:10 Aspect Ratio (PA653U/PA803U—WUXGA)
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:
C = 0.807W – 1.354
NP11FL:
C(Wide) = 1.185W – 1.794 ------ C(Tele) = 1.541W – 1.794
NP12ZL:
C(Wide) = 1.488W – 1.974 ------ C(Tele) = 2.970W – 1.972
NP13ZL:
C(Wide) = 2.961W – 4.844 ------ C(Tele) = 4.737W – 4.844
NP14ZL:
C(Wide) = 0.808W – 1.537 ------ C(Tele) = 1.054W – 1.537
NP30ZL:
C(Wide) = 0.807W – 1.535 ------ C(Tele) = 1.131W – 1.632
NP40ZL:
C(Wide) = 1.323W – 1.763 ------ C(Tele) = 3.034W – 1.539
NP41ZL:
NP42ZL: C(Wide) = 2.929W + 5.143 ------ C(Tele) = 5.878W + 4.320
