Question about Icy Box IB-DK2102-C - 11-Fach USB-C Dual Dock 60W PD

Hello all. I am using the docking station with my laptop Lenovo yoga 530 and would like to attach my monitor HP Pavilion 23xi. However, the docking station does not seem to recognise the monitor. I have tried two HDMI cables and a VGA cable and installed the latest driver. When I plug the cable directly into the laptop everything works fine. Has anyone had the same problem and found a solution? Thank you very much.
