Is there a recommended sequence of turning on my product and peripherals?

• If you turn on your connected computer or video equipment before starting the projector, the projector automatically detects and displays the image source.
  
  If you turn on the projector first, or have multiple pieces of equipment connected, you may need to press the Source Search button on the projector or one of the Source buttons on the remote control to display your image.
