Dual monitor via usb-c hub on a laptop


Hello people. I am trying to get my company laptop, with a fresh fedora 31 install to work with 2 external monitors, that connect via a usb-c hub (which provide 2xhdmi ports, ethernet , and several standard usb).

My issue is that im getting a strange behaviour on my monitors.
The display configuration only seem to recognize one of the ports in xandr, but both monitors pick the same signal.
So i see a screen on my laptop monitor, and the same image in the two external monitors, working as they would if you duplicate instead of extending the desktop.

For what i gather, i should be able to see two distint monitors DP-1 and DP-2 and the laptop monitor eDP-1. But the DP-1 seems to be disconnected.

Again, the monitors are both turned on, and receiving the same signal.
Any advice on how to proceed?

Did your tried graphical tools?

PS: xrandr is for Xorg, Wayland is default in Fedora.

I dont have an NVIDIA card. this is a laptop with intel integrated graphics
The other monitor is the same brand and model.

This is a brand new install of fedora 31 with KDE plasma. It seems to be running xorg
