Connecting video source devices

You only need to connect the projector to a video source device using just one of the
above connecting methods; however, each provides a different level of video quality. The
method you choose will most likely depend upon the availability of matching terminals on
both the projector and the video source device as described below:
Terminal name
HDMI / MHL
Component Video
Video
If the selected video image is not displayed after the projector is turned on and the correct video
source has been selected, check that the video source device is turned on and operating
correctly. Also, check and confirm that the signal cables have been connected correctly.
