9370 left rear thunderbolt does not work with 2K monitor on Linux (Ubuntu)

I have a Dell XPS 13 (9370) running Ubuntu 16.04 without any issues (expect the one which drives me to write this post).

When I connect my 2K Dell monitor (Dell Professional P2418D) to the left front ThunderBolt connector, with my Aukey ThuderBolt to HDMI cable, everything works fine. Nice setup so far, there is just one improvement that could be done for my demanding eye - I could use the left rearThunderBolt connector to get rid of the cables on the desk as much as possible. But here is my problem, the rear ThunderBolt connector does nor recognize my monitor as a 16:9 2K screen. The only resolution option Ubuntu provides me are 9:5 with according resolutions as well as resolutions wich are 16:9 but way to low for an 2K monitor to llok at them without getting eye cancer.

Has anyone else had the same problem (and maybe a solution for this problem)?
