Windows 10, fresh install (ms iso, dell os recovery iso), used drivers from dell website and from intel/windows update - the issue is the same - after installing Intel UHD Graphics 620 driver the laptop display goes black (sound of disconnected device) and it stays like that. When I plug monitor on HDMI it display windows desktop (cannot switch).
The only time when laptop screen works is on default windows graphic driver and in safe mode.
EDIT: more info about issue
- Tried Windows 10 from 1709 to 1909 (same issue there)
- BIOS newest from site (version 1.2.3)
- under Linux it works (nothing strange here)
- for testing purposes tried Windows 8.1 (but no drivers were available)
