external screen on docking station not working anymore

I have a Thinkpad T14s Gen3 AMD and a Lenovo docking station. A few days ago, my external screen, connected to the docking station using DisplayPort, stopped working. I see the login screen of Xfce, but as soon as I log in, the monitor says "no signal". However, I see the name of the monitor in the display settings of Xfce. (I also tried changing the cable. It didn't help.)

If I connect the same monitor directly to my laptop using an HDMI cable, everything works.

Please tell me what additional information you need.
