In order for monitors to be able to be utilized as an extended display via Daisy Chain there must be support for Display port 1.2 and Multi-Stream Transport (MST). MST will allow you to daisy chain monitors with DisplayPort v1.2. Not only do your monitors need to support DP 1.2 and MST but your Graphics Card (GPU) must as well. Daisy chaining can only be done via Display Port. The maximum number of monitors that can be daisy chained while maintaining 1080p would be 4. Below is a chart that will show the resolution break down of connecting multiple monitors.



To connect your PC to multiple monitors using DisplayPort MST:


  1. Verify that the graphics card (GPU) on your PC supports has a DisplayPort 1.2 MST
  2. Connect your PC to the DisplayPort In port on the first monitor.
  3. Then connect to the DisplayPort Out on the first monitor to DisplayPort In port on the second monitor   (Figure 1).
  4. Using the On-Screen Display (OSD) menu, Enable DisplayPort 1.2 on your monitor.
  5. To learn more, refer to the User Manual of your monitor.
  6. Ensure that the last monitor in the chain has DisplayPort 1.2 mode Disabled.

*** Note: MacOS does NOT support DisplayPort daisy-chaining, also known as multi-stream, or MST, on any of their computers, from MacBooks to MacBook Pros to iMac Pros to Mac Pros, even if they sport Thunderbolt 3. ***
