MultiStream Transport or Daisy Chaining

MultiStream Transport (MST) or Daisy Chaining feature enables you to connect multiple external displays to your computer.

The following table displays the computers that support MST along with the maximum resolution that is supported when two or three monitors are connected:

Table 1. MST and Maximum resolutionMST and Maximum resolution
System	Maximum resolution for two monitors	Maximum resolution for three monitors
Latitude 3440/5440/5450	2 x (2560x1440)	3 x (1920x1080)
OptiPlex All-in-One 7410/7420	4K + (2560x1440)	3 x (2560x1440)

NOTE:DisplayPort and Type-C port supports MST; HDMI port does not support MST.

Limitations

If you enable MST on monitors, display audio does not work.
If you reboot with multiple monitors connected, one monitor may display a black screen. As a workaround, unplug and plug in the monitor that is connected to ThinOS.
Do not hot-plug the daisy-chained monitors, as this may cause a black screen issue. You can hot plug the monitor that is connected to the ThinOS client.
If you connect two or three monitors with MST and plug out the monitors, ThinOS stops responding for 15 s to 30 s. When ThinOS stops responding, do not plug in the docking station again. Wait for ThinOS to recover and then plug in the docking station.
If the default resolution of the monitors is more than the maximum resolution that can be supported, the ThinOS client stops responding.
If you hot-plug monitors when ThinOS is displaying screensaver, the monitors display a black screen.
