Projection distance formulas

To use a screen size not listed in this manual, check the screen size SD (m) and use the respective
formula to calculate projection distance.
The unit of all the formulae is m. (Values obtained by the following calculation formulae contain a
slight 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 S420W/S430W/S430Wi:
Screen height (SH)
Screen width (SW)
Projection distance(L) =0.4625xSD-0.0339
For S420/S430/S430i:
Screen height (SH)
Screen width (SW)
Projection distance(L)
