C usb to hdmi does not display video monitor

[gdepeppe98]

I have a C usb hdmi converter. The converter works fine on another HP laptop: I am able to extend the laptop screen on an external monitor. I just bought a new HP Envy and I tried the same converrete, but the monitor does not come on at all. The HDMI output of the Envy works correctly but the C usb does not. Is this a defective desktop? Please advise.

NO Pc told full model nor product ID#

no 2nd PC that works same model nor iD told.

all must be USB_C rated and driver correct loaded.

I hope to provide you the solution for this very annoying problem!!! I

Before proceeding check  if from the specs of your laptop it is possible to connect an external monitor through the type c port (it should be written DispalyPort on the thunderbolt usb-c properties). If so, and you already tried to update several drivers but still nothing happens, I hope to have the solution. I spent almost 3months to fix the isssue after several attempts performed under the supervision of the HP support. You can find the solution in this post I wrote today to be helpful to the HP community: External monitor not working with thunderbolt connector.

Basically you need to change from 0 to 1 an entry of the register file. Keep me posted if that solution works fine!
