What should I do if I see a blue screen with the message “No Signal”?
Check the following:
  • Make sure the cables are correctly connected to your computer or video equipment.

  • 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 Comp 1, Comp 2, S-video, or Video button on the remote control to select the correct 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.
