Your USB-C device needs to support DP-Alternate mode or Thunderbolt™3 on its
USB-C port in order to display your video output to 1 or more displays. Check the
technical specifications of your USB-C device if it supports DP-Alternate mode or
Thunderbolt™3. If the device does not support DP-Alternate mode or Thunderbolt™3,
the AC7046 will not be able to display video onto your Display(s).
Please Note!!! For the AC7046 to be able to display the max resolution of 4K on all
three monitors your PC/Notebook needs to support additionally DP1.4 and DSC
please check the technical specs of your PC/Notebook if DSC and DP1.4 is
For the single monitor setup, the AC7046 Docking station supports a max. resolution
of 4K @ 60Hz via HDMI or DisplayPort (DP).
Dual Monitor (SST/MST)
For the dual monitor setup, the AC7046 Docking station supports a max. resolution of
4K @ 60Hz on HDMI or DisplayPort (DP).
Triple Monitor (SST/MST)
For the triple monitor setup, the AC7046 Docking station supports a max. resolution of
2x 4K @ 30Hz on HDMI or DisplayPort (DP) and the 3rd monitor on 1080P @ 60Hz if DSC is not supported by your laptop. If your laptop does support DSC you will be able
to use a max. resolution of 4K @ 60Hz on all three displays.
SST (Single Stream Transport)
With SST (Single Stream Transport) the connected screens will only show a clone
(copy) of your main screen on the connected screens.
MST (Multi Stream Transport)
MST is part of the DisplayPort 1.2 standard, with which monitors and computers can
support "daisy-chaining". You usually recognize daisy-chaining when the monitor has
both a DisplayPort input and output. You can connect the first monitor to the computer
and the second monitor to the first monitor. If both the monitor and the computer
support MST daisy-chaining, the two screens work as separate screens. Exactly as if
they were connected directly to the computer.
If your notebook supports DP alt mode (DisplayPort alternate mode) it also supports
MST. In this case the AC7046 will work as a USB-C to MST adapter. You will be able
to use the multiple video outputs. The connected screens will be recognized as
separate screens on your laptop / PC and can be used as an extended desktop.
Windows 10 has a short key to switch between the different display modes:
Use: “Windows key + P” an overview of display modes is displayed on your screen.
Please Note!!! MacOS does not support MST Daisy chaining. MacOS only supports
Daisy chaining with the Thunderbolt™3 standard. So the AC7046 will not provide the
desired result for macOS devices. In this case the connected screens only show a
clone (copy) of your main screen on the connected screens also called SST (Single
