Appendix C - Throw Distance - Runco Video Xtreme VX-40d Owner's Operating Manual

Calculating Throw Distance
It is important throw distance be precisely calculated for your installation using the
appropriate formula from the chart below. To calculate throw distance you must know the
screen size and the lens type installed in the projector. In general, the larger you want the
image to be the greater the distance you must allow between the lens and the screen.
NOTES: 1) Throw distance is
measured from the screen to
the center of the projector's
lens. 2) This measurement is not
necessarily parallel to the floor as
the projector and screen may be
inclined.
