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:
- 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 the Search button 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.
- 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:
- Press the function key that lets you display on an external monitor. It’s often labeled with an icon such as , but it may also be labeled CRT/LCD. You may have to hold down the Fn key while 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. Allow a few seconds for the projector to sync up after pressing it.
- 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 Macintosh OS X:
- 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.
- Click the Arrangement or Arrange tab. (If you don’t see this tab, make sure it isn’t hidden by another window.)
- Make sure the Mirror Displays checkbox is selected.
