■ Make sure your computer's resolution setting is correct and dual display is not activated. Ideally, the resolution should be 1024 × 768 to match the projector's native resolution. If this option isn't available, select one of the other compatible video formats listed on page 98. ■ Windows: Right-click the desktop, select Properties, click the Settings tab, and select a different resolution. ■ Macintosh OS X: On the Apple menu, choose System Preferences, then click Display or Displays. Select a different resolution. ■ You also may need to modify existing presentation files if you created them for a different resolution. See your software documentation for specific information. The image isn't rectangular, but trapezoid-shaped. ■ Make sure the projector isn't placed off to one side of the screen, at an angle, or the image won't be rectangular. Place it directly in front of the center of the screen, facing the screen squarely. ■ If you've tilted the projector upward, the image will be broader at the top. Turn on Auto Keystone correction as described on page 61 or hold down the or buttons on top of the projector until the image is rectangular. The image contains static or noise. ■ If you're using a computer cable longer than 6 feet, or an extension cable, the image quality may be reduced. ■ Keep your computer and video cables separated from the power cord as much as possible to prevent interference. ■ The video signal may be split between the computer and the projector. If you notice a decline in the projected image quality when the image is displayed simultaneously on your laptop computer and the projector, turn off the laptop's LCD display. 88 Solving Problems
