Macbook Air M3 only recognizes 1 display
 

Am I doing something wrong? Dell docking station should be compatible.
Display Link new Version
Macbook Air M3 Sonamo 14.7
Monitor: DELL P2422H Connected with HDMI to Docking
Monitor: Samsung U28E590D Connected with Displayport to Docking
I have installed the latest version on my Mac. I have the rights. Problem: When I connect it to my Macbook and close it, only 1 screen is recognized, but the second screen is active and is mirrored, duplicated. I want to expand it, but my Macbook only shows me one screen. I have even changed cables or just connected them individually to see if the Samsung monitor recognizes it at all. What am I doing wrong? According to Dell, this should be possible? Please help :) Thank you guys
