Connecting other devices
In addition to computers, you can connect the following devices to the display:
USB drives, peripherals, and other devices
a microSD card
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.
The display includes one USB Type-C receptacle and one USB 3.0 Type-A receptacle on the convenience panel. The rear connector panel also includes a USB Type-C receptacle and a USB 3.0 Type-A receptacle.
You can connect USB drives, peripherals (such as keyboards), and other devices to these connectors and use the devices with iQ connected computers, and devices installed in the accessory slot, such as the SMART OPS PC.
Note
Connect only drives, peripherals, and devices to the USB Type-A and USB Type-C receptacles. Do not connect USB hubs.
You can connect an external display using the HDMI 2.0 out connector on the bottom connector panel on the back of the display (pictured below). 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.
Note
The image on the external display may be at a lower resolution than the main display. You can change the output resolution by selecting Settings > Display > HDMI Output.
Important
If the connected external display doesn’t support HDCP, the image on the external display is limited to 480p resolution. For full resolution output, connect a display that supports HDCP.
The display includes three 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). This disables the display’s internal speakers. Alternatively, you can connect an external audio system directly to a room computer.
You can also connect an external audio system to the display using the HDMI 2.0 out connector on the connector panel.
In addition, 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 system that has an S/PDIF input to decode this connection to analog. Most external sound bars include a S/PDIF connector.
If you have external sound system with audio return channel (ARC), you can output the display’s audio to the sound system by connecting the display’s HDMI-1 connector on the side connector panel (pictured) to the HDMI Out connector on the sound 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 (see or Managing the display using RS‑232).
Note
Displays are not compatible with centralized remote control systems, such as a universal remote control.
