Projection dimensions calculation methods
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).

NOTE:
B
If 4:3 images are projected onto a 16:9 screen that
has been set using the projection distance for a
16:9 screen, the 4:3 images will overflow the
screen at the top and bottom. In such cases, set
“ASPECT” to “S4:3”. (Refer to page 46 for details.)
*The values obtained from the formulas above are approximate.
For 16:9 aspect ratios, the following formula can be used to calculate the
projection distance.
