Today i recieved my docking station from purism and EVERYTHING (charging, ethernet, keyboard, mouse & monitor) works!
I use it in conjunction with this hdmi to vga adapter and power supply:

BUT i also bought this usb c extension cable (the third one)

When i connect it between the phone and the hub however the video/screen signal does not get transmitted to my monitor.
(Despite the monitor being recognized in the librem 5 settings)
Without using the extension it works great, though.
I already tried these three and non of them actually works:

Thank you very much for this recommendation.
But is 0.8m the longest possible? I would rather have something like 2m if possible.
Would this one also work?

Could get that way faster than ordering from china.
