Troubleshooting black screen issues on HP Notebooks: Click here to view the instructions!

HP Recommended
Product: Elitebook 840 G8
Operating System: Microsoft Windows 10 (64-bit)

I have an external screen connected with a single USB-C wire. The screen also worked as a dock so it charged the notebook as well as being a USB-hub.

 

After using HP Support Assistant to update all the drivers for the notebook I can no longer use the display. It still charges the notebook but the display stays black saying it doesn't get any input.

 

The notebook is an Elitebook 840 G8.
