What should I do if I see the message No Signal?
The projector has an on-screen help system you can use to solve this problem; see Using On-Screen Help
. If the on-screen help does not solve the problem, check the following:
If you're using Mac OS X:
- Make sure the cables are correctly connected. See Setting Up the Projector.
- 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 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 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 , or 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.
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.
- Select System Preferences from the Apple menu and click Display or Displays.
- Click Detect Displays.
- Do one of the following:
Mac OS X 10.6: Click Show displays in the menu bar.
Other versions of Mac OS X: Make sure the VGA Display or Color LCD dialog box is selected. Click the Arrangement or Arrange tab and make sure the Mirror Displays checkbox is selected.
