Only part of the computer image displayed. What should I do?
- Make sure your computer's resolution doesn't exceed UXGA and the frequency is supported by the projector. Make sure the image Position setting is correct on the Video menu. Make sure your computer's resolution setting is correct. Ideally, it should be 1024 W 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 93-94 of your user's manual (CPD-1391R51). If necessary, change your computer's resolution setting as described below. Windows: Right-click the desktop, select Properties, click the Settings tab, and select a different resolution. Macintosh OS 9.x: From the Apple menu, choose Control Panels, then click Monitors or Monitors and Sound. Select a different resolution. Macintosh OS X: From the Apple menu, choose System Preferences, then click Display. 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.
