You can connect an external display using the HDMI Out connector on the connector panel. The external display will show the same image. This is useful when you’re using the display in an auditorium or other large space where it would be beneficial to have a second display.
Alternatively, you can connect an external display using the USB Type-C Out receptacle on the connector panel.
The display includes two speakers and a sub woofer, which are designed to provide sound at the front of a room. You might want to connect an external audio system if you’re providing sound in a larger space.
You can connect the display to an external audio system using the Stereo 3.5 mm Out connector. This disables the display’s internal speakers. Alternatively, you can connect an external audio system directly to a room computer.
In addition to the Stereo 3.5 mm Out connector, the display provides a Sony/Philips Digital Interface (S/PDIF) Out connector. S/PDIF is a digital audio transmission medium. You need an audio system that has an S/PDIF input to decode this connection to analog. Most external sound bars include a S/PDIF connector.
Note
The S/PDIF audio is a fixed-volume output. Adjusting the volume of the display’s speakers does not affect the S/PDIF output.
You can also connect an external audio system to the display using the HDMI 2.0 Out connector on the bottom connector panel.
If you have an external audio system with HDMI ARC (Audio Return Channel) or eARC (Enhanced Audio Return Channel), you can output the display’s audio to the audio system by connecting the display’s HDMI 2 In connector on the side connector panel to the HDMI ARC connector on the audio system’s receiver.
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 connector to connect a third-party external control system to the display.
Note
Displays are not compatible with centralized remote control systems, such as a universal remote control.
