■If you’re projecting a widescreen computer image, adjust the Resolution setting (see page 63), if necessary.

■If you’re projecting an image from a computer with dual display activated, turn dual display off.

The image isn’t square, but keystone-shaped.

If the image isn’t evenly rectangular, adjust its shape as described on page 44.
