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. 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.
