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 4:3 aspect ratio For 16:9 aspect ratio For 16:10 aspect ratio
Screen height (SH) = SD(m) × 0.6 = SD(m) × 0.490 = SD(m) × 0.530
Screen width (SW) = SD(m) × 0.8 = SD(m) × 0.872 = SD(m) × 0.848
Minimum distance (LW) = 1.475 × SD(m) - 23.28 = 1.301 × SD(m) - 23.28 = 1.266 × SD(m) - 23.28
Maximum distance (LT) = 1.770 × SD(m) - 23.66 = 1.562 × SD(m) - 23.66 = 1.520 × SD(m) - 23.66
