Chapter 3
Connecting computers and other devices
In addition to the stereo 3.5 mm out
connector, the display provides a
Sony/Philips Digital Interface (S/PDIF) out
connector (pictured). S/PDIF is a digital
audio transmission medium. You need an
audio receiver that supports S/PDIF to
decode this connection to analog for use
with an external sound bar or other audio
system.
NOTES
The S/PDIF out connector is a fixed-volume output. Adjusting the display's volume for its internal
l
speakers does not affect the volume output of the S/PDIF out connector.
If you connect an audio output device to any of the display's USB Type-A receptacles, all the display's
l
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.
Connecting room control systems
A room control system enables users to control a room's lighting, audio system and, possibly, the display.
Some installations may require you to integrate the display with a room control system.
You can use the display's RS-232 IN connector to connect a third-party external control system to the
display (see Appendix B: Managing the display using RS-232 on page 71).
NOTE
Displays are not compatible with centralized remote control systems, such as a universal remote control.
