Setting-up dimensions which are not given in the above table can be
calculated using the formulas below.
If the screen size (diagonal) is SD (m), then the following formula is used to
calculate the projection distance for the wide lens position (LW) and the
projection distance for the telephoto lens position (LT).

For 16:9 aspect ratios, the following formula can be used to calculate the
projection distance.

NOTE:
B The dimensions in the table above and the values obtained from the

above formulas may contain slight errors.

B If you use the projection distance for the 16:9

screen, the 4:3 projection image overflows the
screen at the top and bottom.
