Laptop Screen flickering, 4k Monitor black and going to sleep

2017-12-18, 12:10 PM

I connected my DELL 4k monitor using my new USB-C dock (Lenovo) + Displayport cable. As soon as I plug in the cable, the laptop screen starts flickering terribly but the external monitor stays black. After a few seconds, it sleeps; the laptop keeps flickering (screen image/black/screen image/black/...).

 

What can I do?

 

I did not change any display settings. Simply unpacked the docking station and connected the monitor.

 

It does not even give me a chance to change any display settings because as soon as it starts flickering, it becomes almost unresponsive.
