Hi,

i have HP EliteDisplay S340c 34-inch Curved Monitor which i'm trying to connect to HP ENVY x360 - 15-cn0017ur over USB type-c 100 w cable.

When i connect display to laptop via usb type-c cable there is a warning: unathorised cable.

USB host works fine, camera also works. But 1) monitor doesn't charge laptop i.e. power on delivery doesn't work 2) video signal doesn't flow from laptop to display. 

HP says 

Q: How will I know if the USB Type-C connector on my device supports DisplayPort over USB Type-C?

A: USB Type-C connectors that support the DisplayPort over USB Type-C will normally include the DisplayPort (DP) logo near the connector.

I don't have such logo on the laptop. I only have ssd logo and power on delivery logo.

It seems that the cable has some limitations. But am i able to use single usb type-c cable for both video signal ang charge at the same time? If yes could someone give a link to a decent one?

just checked - display actually gives current over usb type-c cable - my phone being charged in Quick charge mode

checked usb type-c port with PD on the laptop with another charger - works okay.

Looks like PD problem is in the cable. But the question is still unanswered: am i able with a descent single usb type-c cable for both video signal and charge at the same time? If yes could someone give a link to a decent one?
