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.
