Dual display with usb3 Asus Dock to hdmi

I am trying to connect a secondary monitor on my Manjaro using ASUS dock with usb-3 connector.
It works perfectly well for network cable, and other usb device such as Keyboard/mouse. But I can’t find a way to use the hdmi port from the dock to extend my display. I tried many things regarding xrand / xorg / displayLink (which I installed with no change anywhere)

Hello @marcoooo and welcome :wink:

Not enough information… You could start with this:

inxi -Fazy
lsusb -vt
xrandr --listmonitors --verbose

Disconnect the hdmi cable and run:

journalctl --boot 0 --grep "\([A-Z][A-Z]\)" --no-hostname --follow 

Then connect again and look what is happening there.

Be sure that the hdmi cable is compatible and also that your Laptop is capable to use video over usb-c.
