External display not detected

I recently bought myself a LG 27inch 4k Ergo monitor (27UN880)
When I connect my monitor with my laptop over Type C, Zorin OS (Core) does not detect the monitor.

But when I use the HDMI cable it works. How can I solve this problem?
I want to use the type-c port for display because with type-c this monitor has 2 USB 3 passthrough so thats important for me

Can you please open a terminal while connected to the display, type

sudo lshw -C video

and post back the results?
