Multiple monitors connection using DisplayPort
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.
