Note
f
When [SCREEN ADJUSTMENT] is used, the focus of the entire screen may be lost as correction increases.
f
Make the curved screen a circular arc shape with one part of a perfect circle removed.
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.

Formula for calculating the projection distance
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.

Projected image size
Height (SH)
= SD x 0.530 = SD x 0.490 = SD x 0.6
Projected image size
Width (SW)
= SD x 0.848 = SD x 0.872 = SD x 0.8
Minimum projection distance
(LW)
= 1.2598 x SD - 0.0526 = 1.2949 x SD - 0.0526 = 1.4262 x SD - 0.0526
Maximum projection distance
(LT)
= 2.5118 x SD - 0.0390 = 2.5816 x SD - 0.0390 = 2.8436 x SD - 0.0390
