thanks for replying.
The exact type of the notebook: FX706LI-HX177T (ASUS TUF Gaming F17).
The manual is here:
The port description in the manual (page 25):
“The USB 3.2 (Universal Serial Bus 3.2) Gen 2 Type-C port provides a transfer rate of up to 10 Gbit/s and is
backward compatible to USB 2.0. Use a USB Type-C adapter to connect your notebook PC to and external display.”
I can see the following notations next to the Type-C port on the notebook: 10 and D, is should mean 10 Gbit/s and DisplayPort, so the manual is correct.
The wiring is simple (NB-notebook, DS-docking station):
– The NB has its own powder adapter, it’s always connected.
– The red USB port of the DS power supply is connected to the red Type-C port of the DS.
– The Type-C port of the NB is connected to the input port of the DS (angled connector).
The USB and the Ethernet ports of the DS work properly.
I tried to connect a Samsung full HD monitor to the DS. It has these inputs: analog, HDMI, DisplayPort.
Neither of them work (DS analog -> monitor analog, DS HDMI -> monitor HDMI, DS DP -> monitor DP).
I had an idea: what if the DS tries to power the NB if the DS power supply is connected despite the NB has a power adapter?
I disconnected the power supply of the DS. The result is the same.
I checked it with another notebook (15 inch version, same hardware) – no success.
I’m a bit confused with the DP Alt mode. Are there DisplayPort compatible USB-C ports without DP Alt support OR DP Alt mode == USB-C with DisplayPort support?
