Installation guide

Since audio input is not included in the DVI-I port to XT Codec Unit connection, you need to
make a separate audio connection from the computer’s audio output port into the audio
input port of the XT Codec Unit.
Note
The audio input port supports both analog and digital optical audio.
Step 3
Continue with setting the display resolution, as described in “Selecting the Computer Display
Resolution” on page 26.
