3-Chip DLP™ Projector PT-DW17K2 Calculation of the projection distance For a screen size different from the above, use the equation below to calculate the projection distance. Aspect ratio 16:9 Zoom lenses ET-D75LE6 ET-D75LE10 ET-D75LE20 ET-D75LE30 ET-D75LE40 ET-D75LE8 Fixed-focus lens ET-D75LE50 minimum maximum minimum maximum minimum maximum minimum maximum minimum maximum minimum maximum L (m) = (diagonal screen size in inches) × 0.0231 - 0.0566 L (m) = (diagonal screen size in inches) × 0.0277 - 0.0736 L (m) = (diagonal screen size in inches) × 0.0324 - 0.0857 L (m) = (diagonal screen size in inches) × 0.0419 - 0.1085 L (m) = (diagonal screen size in inches) × 0.0415 - 0.0832 L (m) = (diagonal screen size in inches) × 0.0602 - 0.1162 L (m) = (diagonal screen size in inches) × 0.0598 - 0.1131 L (m) = (diagonal screen size in inches) × 0.1160 - 0.1765 L (m) = (diagonal screen size in inches) × 0.1145 - 0.1577 L (m) = (diagonal screen size in inches) × 0.1826 - 0.1615 L (m) = (diagonal screen size in inches) × 0.1831 - 0.3862 L (m) = (diagonal screen size in inches) × 0.3430 - 0.3598 L (m) = (diagonal screen size in inches) × 0.0176 - 0.0713 • Distances calculated with the above equations will include slight deviations.
