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

• Turn on the computer or video equipment you want to use before you turn on the projector so it can display 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.
