Setting-up dimensions which are not given in the above table
can be calculated using the formulas below.
If the screen size is SD, then the following formula is first
used to obtain the screen width (SW).
SW (m) = SD x 0.0254 5 x 4
The value for SW obtained above can then be used with the
following functions to calculate the projection distance.
LW (m) = 1.98 x SW
LT (m) = 2.57 x SW
For 16:9 aspect ratios, the following formula can be used to
calculate the screen width (SW) and the projection distance
for the wide lens position.
SW (m) = SD x 0.0254 18.36 x 16
