Multi Monitor Requirements
The MTB3-DOCK-02 supports the connection of two monitors at the same
time through DisplayPort Multi-Stream Transport (MST) mode. When
DisplayPort MST mode is in use, the DisplayPort video port must be one of
the two video ports being used. Connect either a DisplayPort monitor and
HDMI monitor or a DisplayPort monitor and VGA monitor. Do not connect an
HDMI monitor and a VGA monitor.
The below limitations 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 Thunderbolt 3 source that supports DisplayPort
MST mode, the EDID information of both connected monitors will be read
by the computer and appear as separate displays that can be shown in
mirror mode or extended mode. Both the DisplayPort and HDMI ports
support full 4K x 2K (3840 x 2160) @ 60 Hz video resolutions and can
be used simultaneously. The VGA port reaches maximum resolutions of
1920 x 1200 @ 60 Hz and can be used with the DisplayPort video port
simultaneously.
When connecting to a Thunderbolt 3 source that does not support
DisplayPort MST mode, such as a MacBook, 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 resolutions of the first monitor will then be sent
to the second monitor, with both monitors displaying the same resolutions.
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.
