Connecting other devices
In addition to computers, you can connect the following devices to the display:
USB drives, peripherals, and other devices
External displays
External audio systems
Room control systems
Warning
Ensure that any cables that cross the floor to the display are properly bundled and marked to avoid a trip hazard.
Connecting USB drives, peripherals, and other devicesThe display includes two USB 3.0 Type-A receptacles on the convenience panel and three USB 3.0 Type-A receptacles on the connector panel. You can connect USB drives, peripherals (such as keyboards), and other devices to these connectors and use the devices with the iQ experience, connected computers, and devices installed in the accessory slot (such as the SMART OPS PC module).
The following table shows which USB 3.0 Type-A receptacles you can use with each input source and the supported USB speed:

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.
Connecting an external display
You can connect an external display using the HDMI 2.0 out connector on the connector panel (pictured). 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.
You can set the default resolution for the HDMI 2.0 out connector in the settings (see System settings).
Connecting an external audio systemThe display includes two 15 W speakers, 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 an external audio system to the display using the stereo 3.5 mm out connector (pictured). 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 (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 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 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 systemsA 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 Managing the display using RS‑232).
Note
Displays are not compatible with centralized remote control systems, such as a universal remote control.
