Librem 15v4 Docking Station & HDMI

Hi,

I have a i-tec USB 3.0 Docking Station.

When I attach the monitor directly through the HDMI cable with the computer, then the monitor is recognized by the computer.
However, when the cable is attached to the HDMI port of the docking station, then no monitor is detected by the Librem 15v4.

All USB devices attached to the docking station are working fine. The same setup works with a Windows laptop (monitor shows laptop desktop while HDMI cable is only attached to the docking station).

What could be the problem and what could I do about this?

Further, the lower right USB port of the Librem 15v4 as well as the upper left USB port do not recognize the docking station. Only the lower left and upper right USB ports do (although it is another issue).

Regards,

The problem could be that the Librem 15 does not support video output via USB-C at all.

Thank you very much for your reply and help!
