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 EX50 and EX70 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 EX30projector, do
one of the following:
■ Press the appropriate keystone correction button on the
projector’s control panel until the shape is evenly rectangular.
