Multiple monitors connection
You can daisy-chain monitors to each other using the DisplayPort OUT/IN connections on the monitors.
For using connected monitors in MST (multi-stream transport) mode, the setting should be DP OUT MULTISTREAM “AUTO” for
each monitor. Please change the setting for the monitor that connects to the computer last.
If the monitors do not display an image, turn off the monitor connected to the computer then turn it back on.
Configuring the DisplayPort connections may be necessary. Please refer to the table below and change the settings as needed.

OOTEN: • The number of monitors that can daisy-chain, from a single connection to the computer, depends on the display
adapter capabilities and its settings. Please refer to the user instructions for the computer or display adapter.
• When [DP OUT MULTISTREAM] is set to [AUTO], we recommend setting [VIDEO DETECT] to [NONE]. It might
contribute to better stability at returning from Power saving or power OFF.
• When using the USB-C port to connect to a computer and MST is enabled on the monitor, the device may detect
and connect as a Hi-Speed (USB 2.0) device even if it complies with SuperSpeed (USB 3.0).
In this situation, the USB hub is temporarily disconnected when switching between SuperSpeed and Hi-Speed.
