Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
•
Distances calculated with the above equations will include a slight error.
minimum
L (m) = (diagonal screen size in inches) × 0.027400 - 0.055400
maximum
L (m) = (diagonal screen size in inches) × 0.037200 - 0.053400
minimum
L (m) = (diagonal screen size in inches) × 0.036000 - 0.050400
maximum
L (m) = (diagonal screen size in inches) × 0.061300 - 0.049700
minimum
L (m) = (diagonal screen size in inches) × 0.061320 - 0.113900
maximum
L (m) = (diagonal screen size in inches) × 0.099950 - 0.112800
minimum
L (m) = (diagonal screen size in inches) × 0.100200 - 0.212700
maximum
L (m) = (diagonal screen size in inches) × 0.159120 - 0.210700
(fixed focus)
L (m) = (diagonal screen size in inches) × 0.017517 - 0.057231
