120 Appendix A: Projector Installation
Using the Lens Shift is better than angling the projector up or down
to position the image, since it won’t produce keystone distortion,
which must be eliminated electronically.
If you mount the projector on the ceiling above screen level, you’ll
have to tilt it down to center the image on the screen. This causes the
image to lose its square shape, but you can correct the distortion by
using the
Keystone function in the projector’s menu system (see
page 71) or by pressing the Keystone button on the projector’s
control panel.
Installing the Rear Cable Cover
If you’re mounting the projector on the ceiling, you can install the
rear cable cover to enhance the cosmetic appearance of the system.
To install the cover, insert the cover’s tabs into the slots as shown,
then push the cover against the projector until it locks into place.
note
If you’ve installed the
wide-angle rear projection
lens, you won’t be able to use
the projector’s Focus, Zoom,
or Lens Shift functions. You
must position the projector
itself to obtain the desired
image height, size, and focus
(but Keystone correction can
still be used).
