Chapter 4 Connecting computers and other devices
Note
If you connect an audio output device to any of the display's USB Type-A receptacles, all the display's
audio output will be routed through this audio output device rather than through the display's internal
speakers or any external audio systems connected to the stereo 3.5 mm out connector or the S/PDIF
out connector.
