Formulas: 16:9 Aspect Ratio (PH1202HL—1080)
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:
NP-9LS08ZM1: C(Wide) = 0.912W – 2.094 ------ C(Tele) = 1.369W – 2.094
NP-9LS12ZM1: C(Wide) = 1.283W – 2.118 ------ C(Tele) = 1.833W – 2.118
NP-9LS13ZM1: C(Wide) = 1.423W – 2.189 ------ C(Tele) = 2.250W – 2.189
NP-9LS16ZM1: C(Wide) = 1.726W + 2.205 ------ C(Tele) = 2.891W + 2.205
NP-9LS20ZM1: C(Wide) = 2.222W + 3.024 ------ C(Tele) = 4.156W + 3.024
NP-9LS40ZM1: C(Wide) = 4.278W - 4.110 ------ C(Tele) = 6.739W – 4.118
