44 Displaying and Adjusting the Image
Adjusting the Image Shape
You can maintain a rectangular image by placing the projector directly
in front of the screen and keeping it level. This also produces the best
picture quality. If the projector is tilted up or down (up to 30°), or
placed at an angle, the shape may “keystone” and you may need to
correct the image shape.
The PowerLite 78 and PowerLite W6 Series projectors include an
Auto Keystone function that detects and corrects vertical keystone
distortion up to 11°. It takes about one second after the projector
starts for the image to be corrected.
If your image is still distorted, or you are using the PowerLite S6
Seriesprojector, do one of the following:
■ Press the appropriate keystone correction button on the
projector’s control panel until the shape is evenly rectangular.
