Displaying and Adjusting the Image 25
Turning the Projector On and Off
Turn on any connected computer or video equipment before starting
the projector so it can automatically detect and display the image
source. If you turn on the projector first, or have multiple pieces of
connected equipment, you may have to select the image source
manually (see page 28).
Follow these steps to turn on the projector:
1. Make sure the power cord is connected and the projector is
plugged into an electrical outlet.
