Formulas for calculating dimensions
To use a projected image size not listed in “Dimensional relationship” (
x
page 8), check the projected image size
SD (m) and use the respective formula to calculate the value.
Values obtained with the following formulas 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.

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 (L)
= 0.1782 × SD + 0.0485
= 0.1831 × SD + 0.0485
= 0.2017 × SD + 0.0485
Distance from screen surface to back
surface of the projector (L1)
= 0.0100 + (L - 0.4105)
Distance from back surface of the projector
to wall surface (L2)
= L1 + D
Distance from wall surface to center axis
of horizontal swing adjustment (L4)
= L1 + L3 + D or
= 0.0100 + (L - 0.4105) + L3 + D
Distance from top edge of projected image
to center of screw holes (on lower side)
used for securing the wall mount bracket
(H1)
= 0.0933 × SD + 0.1564
= 0.1231 × SD + 0.1564
= 0.1056 × SD + 0.1564
Distance from top edge of projected image
to center of screw holes (on the upper
side) used for securing the wall mount
bracket (H2)
= 0.0933 × SD + 0.3294
= 0.1231 × SD + 0.3294
= 0.1056 × SD + 0.3294
