Set up multi-screen displays with Multi-Stream Transport (MST) by following below steps:
1. Power on all monitors and enable DisplayPort 1.2 and/or MST in the settings menu of each monitor
2. Connect your laptop to monitor 1 by one of two ways:
• Connect the "DisplayPort Out" on your laptop to the "DisplayPort In" on the monitor using a DisplayPort cable
• Or, connect the "DisplayPort over the USB-C Out" on your laptop to the "DisplayPort over USB-C In" on the monitor using a USB-C cable
3. Connect the "DisplayPort Out" on monitor 1 to the "DisplayPort In" on monitor 2 using a DisplayPort cable
4. Repeat step 3 for subsequent monitors
NOTE:
* If using Mac, try with a Windows system. MST is available on Mac OS via Thunderbolt connection only
* Please make sure that your graphic card supports DP 1.4 for MST and note that the supported number of monitors for connection may vary by graphic card
