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 formulas is m. (Values obtained by the following calculation formulas 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 PT-LW376
16:10 aspect ratio 16:9 aspect ratio 4:3 aspect ratio
Screen height (SH)
= 0.530 × SD = 0.490 × SD = 0.6 × SD
Screen width (SW)
= 0.848 × SD = 0.872 × SD = 0.8 × SD
Minimum distance (LW)
= 1.2692 × SD - 0.025 = 1.3045 × SD - 0.025 = 1.4369 × SD - 0.025
Maximum distance (LT)
= 1.5249 × SD - 0.025 = 1.5673 × SD - 0.025 = 1.7263 × SD - 0.025
For PT-LW336
16:10 aspect ratio 16:9 aspect ratio 4:3 aspect ratio
Screen height (SH)
= 0.530 × SD = 0.490 × SD = 0.6 × SD
Screen width (SW)
= 0.848 × SD = 0.872 × SD = 0.8 × SD
Minimum distance (LW)
= 1.2660 × SD - 0.02327 = 1.3008 × SD - 0.02327 = 1.4332 × SD - 0.02327
Maximum distance (LT)
= 1.5195 × SD - 0.02367 = 1.5615 × SD - 0.02367 = 1.7202 × SD - 0.02367
