Projection distance
A ±5 % error in listed projection distances may occur.
When [SCREEN ADJUSTMENT] is used, distance is corrected to become smaller than the specified image size.

Projection distance formulas
Any other projection distance can be obtained according to the screen dimensions (m) by using the following
calculations.
The calculated distance may contain a certain error.
If you want to calculate the projection distance with projected image size SD (unit: inch) by substituting, please
assign 0.0254 times to the SD value.
For 4:3 aspect ratio
For 16:9 aspect ratio
For 16:10 aspect ratio
Screen height (SH)
= 0.6 × SD
= 0.490 × SD
= 0.530 × SD
Screen width (SW)
= 0.8 × SD
= 0.872 × SD
= 0.848 × SD
Minimum distance (LW)
= 0.9461 × SD - 0.0295
= 1.0307 × SD - 0.0295
= 1.0028 × SD - 0.0295
Maximum distance (LT)
= 1.5324 × SD - 0.0272
= 1.6696 × SD - 0.0272
= 1.6244 × SD - 0.0272
