When I add a USB-Type C adapter for HDMI and VGA to the USB-C port, then it does not work.

So my question is:
Does the error come from my HP notebook or from another device?

 

 

Solution:

 

You must press Fn-ESC to get the information screen of your HP notebook.
On the bottom there is the USB-C port. Press on it and you will see if the Display Port is supported or not.

DisplayPort :   (not) supported


In my case it is not supported.
