What should I do if I see the message No Signal?
Try the following solutions:
- Make sure that all the cables required for projection are securely connected.
- 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's control panel or one of the Source button on the remote control to select the correct image source.
- 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.
- If the function key doesn't let you display simultaneously on both screens, you might need to use the Display utility in the Windows Control Panel to make sure that both the LCD screen and external monitor port are enabled. From the Windows Control Panel, open the Display utility. Click the Settings tab, then click Advanced. The method for adjusting the setting varies from computer to computer; you may need to click a Monitor tab, then make sure the external Monitor port is set as your primary display or enabled. See your computer manual or online help for details.
If you're using a Mac laptop:
Changing the Projected Image
Connecting to an External Monitor

- Select System Preferences from the Apple menu and click 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.
