Hello, I recently purchsed (HP Notebook - 14-cf1506sa) and I have been having troubles getting an external monitor to work from the USB Type-C port, I have updated Windows 10 to the latest version, installed the latest drivers from Intel and HP support, I have repeatedly reinstalled the drivers on device manager, as the monitor comes up as an error, tried updating the drivers in any way I can and have come up with nothing.
The HDMI port successfully allows one external monitor as expected, but the USB Type-C to HDMI cable I am trying to use which uses the Display Port Alt protocol cannot display the monitor, I have changed monitors and tried the cable on another laptop that successfully runs a monitor from USB Type-C and the monitor and cable both work.
I have tried to research if the Notebook actually has the Display Port Alt protocol to allow Type-C to be used for a monitor but I cannot find that information anywhere, I have checked the entire documentation and looked online and there is nothing, all I found was on Curry's the product description does mention that the USB Type-C can be used in this way, however that is a single source.
Any help would be really appreciated.

Well, since the USB-C port does not have the display port function "DP" no matter what device you get it won't work with USB-C port. I'm sorry for that but this is how the port works there are different versions of the port and some of them have DP and some don't.
However you can try to get a HDMI splitter but I am not sure of the functionality of that one and how the unit will react to it.
