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.
