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.
