Q:
Why am I getting a blue screen with the message "No Signal" displayed?
A:
Make sure the cables are installed correctly, as described in your User's Guide. Try restarting your computer. If you've connected a computer and one or more video sources, you may need to press the Source button (on the projector) or the Computer or S-Video/Video button (on the remote control) to select the correct source. Allow a few seconds for the projector to sync up after pressing the button. If you're using a PC laptop: Hold down the Fn key and press the function key that lets you display on an external monitor. It may have an icon labeled CRT/LCD. Allow a few seconds for the projector to sync up after pressing it. Check your laptop's manual or online help for details. On most systems, the CRT/LCD key lets you toggle between the LCD screen and the projector, or display on both at the same time. Depending on your computer's video card, you might need to use the Display utility in the Control Panel to make sure that both the LCD screen and external monitor port are enabled. See your computer's documentation or online help for details. If you're using a PowerBook or iBook with Macintosh OS 9.x: 1. From the Apple menu, select Control Panels, then click Monitors or Monitors and Sound. 2. Click the Arrange icon. 3. Drag one monitor icon on top of the other. This lets you display on the projector screen as well as the LCD screen. 4. If the Arrange icon isn't available, click the Monitor icon. 5. Select one of the listed Simulscan resolutions. (Allow a few seconds for the projector to sync up after making the selection.) If you're using a PowerBook or iBook with Macintosh OS X: 1. From the Apple menu, select System Preferences, then click Display. 2. Select the VGA Display dialog box, click the Arrange tab, then put a check mark in Mirror Displays.
