Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
Aspect ratio 16:10

maximum L (m) = (diagonal screen size in inches) × 0.03660
Aspect ratio 16:9
minimum L (m) = (diagonal screen size in inches) × 0.03429
maximum L (m) = (diagonal screen size in inches) × 0.03764
