I see the message No Signal. What should I do?
You can use the projector's on-screen help system to solve this problem; see Using On-Screen Help. If the on-screen help does not solve the problem, check the following:
- Make sure the cables are correctly connected. See Connecting to a Computer.
- Make sure the power to your computer or video equipment is turned on.
- If you've connected a computer and one or more video sources, you may need to press the Source Search button on the projector or one of the source buttons on the remote control to select the correct source. Allow a few seconds for the projector to sync up after pressing the button.
- Try restarting your computer.
- Try another cable.
- If you've connected a laptop computer with a VGA cable, make sure it's set to display on an external monitor. If you're using a PC notebook:
- Hold down the Fn key on the keyboard and press the function key that lets you display on an external monitor. It may have an icon such as , but it may be labelled CRT/LCD. Allow a few seconds for the projector to sync up after pressing it. Check your notebook's manual or online help for details.
On most systems, the 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.
- Make sure the projector is connected to your Macintosh.
- Select System Preferences from the Apple menu and click Display or Displays.
- Click Detect Displays.
- Make sure the VGA Display or Color LCD dialog box is selected.
- To display the entire desktop on both your projector screen and LCD screen, click the Arrangement or Arrange tab. (If you don't see this tab, make sure it isn't hidden by another window.)
- Click Mirror Displays in the lower corner of the screen. One of the monitor icons automatically moves on top of the other.
