What should I do if I see a blue screen with 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.
- Try restarting your 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. See Selecting the Image Source. Allow a few seconds for the projector to sync up after pressing the button.
- If you’ve connected a laptop computer, make sure it’s set to display on an external monitor. Try the following:
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.
- 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.
