Hardware Installation

Make sure all devices are powered off and unplugged.1.

Connect the DVI video source (i.e. computer, HDTV box, etc.) to 2.
the Input connector on the splitter, using a standard male/male DVI
cable. If using audio, also connect a 3.5mm mini-jack audio cable
from the video source to the Input connector on the splitter.

sources may default to using an analog signal, when a DVI-I cable
is used.

to one of the Output connectors on the splitter, using standard
male/male DVI cables. If using audio, also connect a 3.5mm mini­jack audio cable from the Output connector to the display device/
speakers.
