Connect multiple monitors to devices without USB4/Thunderbolt 4

You can daisy chain up to eight monitors by connecting a series of display devices using a wired connection from monitor to monitor in a series, rather than connecting each monitor directly to Surface Thunderbolt 4 Dock.

To daisy chain monitors, you need two or more monitors that support at least DisplayPort 1.2 and Multi-Stream Transport (MST). Displays that function as a middle link in the chain must include DisplayPort output ports and input ports. You also need a video or graphics card (GPU) on your PC that supports DisplayPort 1.2 and MST.

Note

Resolution and refresh rate is reduced when daisy chaining two or more monitors.

To connect your PC to multiple monitors using DisplayPort MST:

  1. Connect your PC to the DisplayPort-In connection on the first monitor.
  2. Connect the DisplayPort-Out connection on the first monitor to the DisplayPort-In connection on the second monitor. To daisy chain more than two monitors, follow a similar sequence: The first monitor connects to the second, the second monitor connects to the third, and so on.
  3. Use the On-Screen Display (OSD) menu, to enable DisplayPort 1.2 on your monitor. To learn more, refer to the user manual of your monitor.
