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 47 for details.)

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).

4:3

LW/LT

*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.

LW=0.028xSD/0.0254-0.042

LT=0.033xSD/0.0254-0.043
