Macintosh: For a Macintosh, choose Control Panels under the Apple menu and then choose Monitors. In the Monitors screen, choose Options and make sure Macintosh Hi-Res Display or another 1024 × 768 (PowerLite 7250 or 7350) and 800 × 600 (PowerLite 5350) display is selected. For supported display settings, see "Supported Monitor Displays" on page 156. You also may need to modify existing presentation files if you created them for a different resolution. See your software manual for specific information. ◗ The message NO SIGNAL is displayed. An image source not connected to the projector is selected, the signal is not being output from the computer, or the signal is not reaching the projector. Make sure the connectors are securely attached to both the projector and the image source. Then check that the image source is selected correctly. If your projector is attached to a Macintosh, make sure that the DIP switches on your Macintosh desktop adapter are set correctly. (See your Macintosh documentation if you need instructions.) When NO SIGNAL is displayed, you cannot access the Video menu. ◗ A blank screen is displayed. The computer signal cannot be interpreted by the projector. Verify the display format (see page 156). When you see a blank screen, you cannot access the projector menus. Problems with the Image or Sound 149
