Screen connected with DisplayPort and OneLink+-Dock does not work

Hi there,
i just bought a OneLink+-Dock (not the OneLink Pro-Dock, I had to learn the difference myself) for use in combination with my Lenovo Thinkpad 13 running Arch. My main aim is to be able to use a multi-monitor setup, just because the notebook has only one HDMI-output. USB, analog sound and LAN work perfectly well when connected to the Dock, but I have no clue what to do about the screens.
I tried both of the DisplayPort-outputs, without any success, neither the KDE settings show the new screen nor 'xrandr --query' differs from the output without the additional screens. Unfortunatly the same applies to the VGA-output.

Notes:
- The BIOS setting is set correctly (so the notebook should use OneLink for additional screens, instead of USB-C).
- I don't have a DisplayPort screen, but I tried DisplayPort <-> DVI and DisplayPort <-> HDMI adapters/cabels with no success.

Any help?
