Image Shape
You can project an evenly rectangular image by placing the projector directly in front of the center of the
screen and keeping it level. If you place the projector at an angle to the screen, or tilted up or down, or off
to the side, you may need to correct the image shape for the best display quality. After correction, your
image is slightly smaller.
For the best quality images, try to adjust the projector's position to achieve the correct image size and
shape. After you have corrected the position of the projector, you can use the adjustments in this section
to correct the image shape. You cannot correct an image shape using multiple correction methods at the
same time.
Note: For interactive use, the image must be evenly rectangular, without distortion. Refer to the online
Installation Guide for instructions on positioning the projector to achieve an evenly rectangular image.
After performing any Geometry Correction, you need to calibrate the system again.

Correcting Image Shape with the Keystone Buttons
You can use the projector's keystone correction buttons to correct the shape of an image that is
unevenly rectangular on the sides.
Note: You can use the keystone buttons to correct the image up to ± 3° horizontally or vertically. If the
projector is mounted on the wall, use the adjustment dials on the wall mount to correct the screen image
before using any other digital correction methods.
Note: If you change the Screen Type setting or adjust the image position, your image adjustments are
reset.
