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
minimum
L (mm) = (diagonal screen size in inches) × 20.1 – 56.6
maximum
L (mm) = (diagonal screen size in inches) × 24.1 – 73.6
minimum
L (mm) = (diagonal screen size in inches) × 28.4 – 85.7
maximum
L (mm) = (diagonal screen size in inches) × 36.7 – 108.5
