■If you’re projecting from a computer or RGB video device, press the Auto button on the remote control. If this doesn’t work or if you’re projecting from a component, composite, or S-Video device, you may need to adjust the Position setting in the Signal menu. See page 59 for more information.

■If you’ve enlarged part of the image using the E-Zoom button on the remote control, press the Esc button to cancel zooming and return to full display.

■Try pressing the Resize button on the remote control to select a different aspect ratio (ratio of length to height).
