I installed the new version, it seems to fix the problem
Version 27.20.100.9565, A06
- Fixed the issue where the monitor does not display when it is connected to the system through Dell D6000 dock.
- Fixed the issue where the system displays a black screen when you close the lid and restart the system through the external monitor.
