Adjusting the Height of Your Image
If the image is too low, you can raise it by extending the projector’s
front adjustable foot.
1. Stand behind the projector. Press up on the blue foot release
lever and lift the front of the projector to extend the front
adjustable foot.
2. Once the image is positioned where you want, release the lever to
lock the foot in position.
If the image is no longer rectangular after raising it, see the next
section.
Adjusting the Image Shape
If the projector is tilted up or down, the images that are displayed will
be distorted. To correct the distortion or “keystone” shape, do one or
more of the following:
■ If your image looks like or , you’ve placed the projector
off to one side of the screen, at an angle. Move it directly in front
of the center of the screen, facing the screen squarely.
note
The PowerLite 77c
automatically corrects
images that are distorted
when the projector is tilted
up or down (up to a 30
°
tilt). The Keystone window
appears on the screen while
the projector makes the
correction. If the projected
image still isn’t rectangular,
follow the instructions on
this page.
