Projection distance formulas
To use a projected image size not listed in this manual, check the projected image size SD (m) and use the
respective formula to calculate the value.
The unit of all the formulae is m. (Values obtained by the following calculation formulae contain a slight error.)
When calculating the value using image size designation (value in inches), multiply the value in inches by 0.0254
and substitute it into SD in the formula.
For PT-TMZ400, PT-TMW380
Aspect ratio 16:10 16:9 4:3
Screen height (SH) = 0.530 × SD = 0.490 × SD = 0.6 × SD
Screen width (SW) = 0.848 × SD = 0.872 × SD = 0.8 × SD
Projection distance

When not using Digital
Zoom Extender
= 0.3774 × SD - 0.0332 = 0.3879 × SD - 0.0342 = 0.4273 × SD - 0.0376
When using Digital
Zoom Extender
= 0.3774 × SD / X - 0.0332 = 0.3879 × SD / X - 0.0342 = 0.4273 × SD / X - 0.0376
*1 X in the formulas represents the setting value of [DIGITAL ZOOM EXTENDER] (100%=1.00, 99%=0.99, ...).
