Hello. Unfortunately, I'm the new one, who’s experiencing the black screen problem.

Samsung 9 Pro notebook NP940X5N-X01US.

All the other things works good, I still can use my notebook with the external monitor connected via HDMI port (or connected thru the USB Type-C dock station, it doesn't matter).

The touchscreen and webcam works fine, but the screen itself remains black all the time. The notebook screen couldn’t be seen as the hardware item not In the Windows display settings menu, not even in the reports from system checking programs like AIDA64. The only one display available is the external monitor. Doesn't matter if the computer is running on battery or plugged in.

May be this issue could be a result of Windows 10 update, I’m not sure. It would be great to get any kind of support from Samsung team and Community. Thank You.
