Any other projection distance can be obtained according to the screen dimensions (m) using the following
calculations.
The distance is shown in units of meters. (The calculated distance may contain a certain error.)
If the screen dimensions are written as “SD",
For 16:10 aspect ratio For 4:3 aspect ratio For 16:9 aspect ratio
Screen height (SH) = SD(m) × 0.530 = SD(m) × 0.6 = SD(m) × 0.490
Screen width (SW) = SD(m) × 0.848 = SD(m) × 0.8 = SD(m) × 0.872
Projection distance (L) = 0.44157 × SD(m) - 0.036768 = 0.49988 × SD(m) - 0.036768 = 0.45386 × SD(m) - 0.036768
Note
Install the projector where the projection distance should be within 63.6cm and 120cm in order to keep the lens
