Getting my Monitor work with the Laptop through DisplayLink

Hi there,

I have a new usb-c docking station where i want to attach my laptop and use the monitor which ist connected with display port to the docking station.
Ive looked at the arch wiki (DisplayLink - ArchWiki) and tried to get the monitor running, so far no luck.

Im a relative beginner in the linux world to keep in mind.

Here is the actual status

I have installed the necessary drivers from the AUR according to the arch wiki.
I have created the /etc/X11/xorg.conf.d/20-evdi.conf file and filled it according to the arch wiki
using xrandr --listproviders in console gets the following results

Providers: number : 2
Provider 0: id: 0x44 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 3 associated providers: 1 name:modesetting
Provider 1: id: 0x26e cap: 0x2, Sink Output crtcs: 4 outputs: 3 associated providers: 1 name:NVIDIA-G0

After that i used xrandr --setprovideroutputsource 1 0

Now the Monitor schould work, but nothing happens…has anyone any idea?
