I see the message No Signal. What should I do?
Try the following:
- Make sure the cables are correctly connected. See Connecting to a Computer.
- Make sure the power to your connected equipment is turned on.
- If you've connected a computer and one or more video sources, you may need to press the Search button or one of the Source buttons on the remote control, or the Source Search button on the projector to select the correct source. Allow a few seconds for the projector to sync up after pressing the button.
- Try restarting your computer.
- If you've connected a laptop computer, 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 also be labeled CRT/LCD. Allow a few seconds for the projector to sync up after pressing it. Check your laptop's manual or online help.
On most systems, the key lets you toggle between the LCD screen and the projector, or display on both at the same time.
If you connect the notebook while the projector or computer are already turned on, the function Fn key that changes the computer's image signal to external output may not work. Turn the computer and the projector off and then back on again.
- 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 Displays.
- Click Detect Displays.
- 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.
