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 remote control until you see the image you want to project. Or, by pressing the button for the source you want on the remote control (Computer, Video, USB, or LAN). If there is more than one port for that source, press the button again to select the other source. See Selecting an Image Source.
