Computer data compatibility
This projector accepts up to 91 kHz horizontal scanning frequency and 162 MHz dot clock.
NOTE:
The projector is not fully compatible with RGB signals of which dot clock is higher than 100 MHz.
The display resolution of this projector is 1024 x 768 pixels. If the display resolution indicated in the above data does not match this reso-
lution, the input signal will be converted to 1024 x 768 pixels.

A: Distance to screen
E: Height from the edge of screen to
center of lens
NOTE:
Illustrations show the projector installed
using optional ceiling bracket.
This illustration is not drawn to scale.
* This distance is especially recommend-
ed for ceiling-mounted use and other
permanent installations.
NOTE:
Values shown are approximate.
The value for L (distance to screen)
varies slightly depending on the zoom
lens characteristics.
When the shortest projection distance is
used, a small amount of distortion may
occur in the image due to the zoom lens
characteristics.
