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 PT-VW355N
For 4:3 aspect ratio
For 16:9 aspect ratio
For 16:10 aspect ratio
Screen height (SH)
= 0.6 × SD(m)
= 0.490 × SD(m)
= 0.530 × SD(m)
Screen width (SW)
= 0.8 × SD(m)
= 0.872 × SD(m)
= 0.848 × SD(m)
Minimum distance (LW)
= 1.1363 × SD(m) - 0.0290
= 1.0316 × SD(m) - 0.0290
= 1.0037 × SD(m) - 0.0290
Maximum distance (LT)
= 1.8422 × SD(m) - 0.0292
= 1.6725 × SD(m) - 0.0292
= 1.6273 × SD(m) - 0.0292
For PT-VX425N
For 4:3 aspect ratio
For 16:9 aspect ratio
Screen height (SH)
= 0.6 × SD(m)

Screen width (SW)
= 0.8 × SD(m)
= 0.872 × SD(m)
Minimum distance (LW)
= 0.9461 × SD(m) - 0.0295
= 1.0307 × SD(m) - 0.0295
Maximum distance (LT)
