DisplayPort Audio User Guide
The DisplayPort interface is used to connect computers and displays. The interface can include audio signals in the same
cable as the video signals. In addition, most DisplayPort Sources (computers) support dual-‐mode, where DVI or HDMI
signals can be sent from the DisplayPort connector using a low-‐cost cable adaptor. DisplayPort dual-‐mode Sources and
adaptors may be marked with the “DP++” icon.
