MacBook Pro Crashes when connected with external display (samsung c34H89)

Guys I have 13" Macbook Pro 2017 (no touch-bar) with Catalina 10.15.4 which is connected onto external monitor Samsung c34H89.


If I forget to disconnect MBp, next morning I wait that MBp reboot and let me know it crashed...


I contacted support and they say it is external monitors fault... but here I see a lot of same or similar trouble with all kind of monitor and even LG's...


Anybody know solution to this issue?

To trouble shoot I would try a different cable, a different port to test, a different adapter.


Apple branded is always preferred over third party for this reason.
