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.
