Using docking staion, second external screen stuck with two resolutions.

[speedball]

Hi,

I'm running Ubuntu 18.04 on a Dell Lattitude 5480 with i-tec USB-C Dual docking station and two Iiyama ProLite XB2481HS screens.
My second screen hooked up with DP <-> HDMI cable is stuck with two resolutions (800x600 and 1024x768) and is not being recognized by Ubuntu.

This is what I'm seeing in dmesg

I'm trying to figure out if this is an issue related to DisplayLink, docking station, or graphic card driver.
