Multi Monitor Requirements
The U442-DOCK4-S supports the connection of three monitors at the same time through
DisplayPort Multi-Stream Transport (MST) mode. Below are limitations that must be
taken into account when connecting multiple monitors at the same time.
Does the Source Computer Support DisplayPort MST Mode?
When connecting to a USB-C source that supports DisplayPort MST mode, the EDID
information of the two or three connected monitors will be read by the computer and
appear as separate displays that can be shown in mirror mode or extended mode. When
connected in MST mode, the computer graphics card will have a total bandwidth of 10.8
Gbps for all video ports.
When connecting to a USB-C source that does not support DisplayPort MST mode,
Single-Stream Transport (SST) mode is used instead. In SST mode, only the EDID of
the first connected monitor is read by the computer, forcing the connected monitors to
display in mirror mode. The default resolution of the first monitor will then be sent to the
second monitor and/or third monitor, with all monitors displaying the same resolution.
If the second monitor is not capable of supporting the same resolution as the first,
no video will display on that monitor. Before connecting the second monitor, the first
monitor's resolution must be changed to the second monitor's resolution in order for
video to be displayed.
Note: The following table depicts the maximum resolution achieved on each video port,
based on the connected monitors. Mac does not support DisplayPort MST; therefore,
multiple monitor setups are not guaranteed.

1) Supports 3 displays to work simultaneously under MST mode,
3 videos share max 10.8 Gbps bandwidth (e.g., dual 1080p/60 Hz,
2) Some host PCs only support output of 3 video streams/monitors.
To ensure the output of the 3 displays, turn off the screen of the host PC.
