USB-C to HDMI out adapter not working (Envy 13'')

[samuele-m]

Hi all, a few months ago I bought an ENVY 13-ah0503na (specs: https://support.hp.com/gb-en/document/c06058339) and I have so far been impressed and happy with it.

The main issue is that the hdmi-out doesn't seem to be working, I'm using the USBC-to-HDMI adapter that came in the box with the laptop and all that happens is that my main screen flickers and the sounds for "new device plugged / device unplugged" keep going on. This is happening both on Windows (10 pro, 64bit) and Ubuntu (18.04 LTS, 64bit).

Why can that be? I haven't used any 3rd party hardware, how comes the adapter this laptop comes shipped with doesn't work?

@samuele-m Here's the best way to resolve this issue:

Turn off USB selective suspend after installing windows & HP updates:

1. Press Windows Key + S and enter control panel.
2. Select Control Panel from the list of results.
   
   
    
3. When Control Panel opens, go to Power Options.
   
   
    
4. Power Options window will now open.
5. Locate your power plan and click on Change plan settings.
   
   
    
6. Click on Change advanced power settings.
7. Go to USB settings > USB selective suspend setting and set it to Disabled.
8. Click on Apply and OK to save changes.

Hi, thanks for the answer and sorry for the belated reply.

The option you suggest couldn't work unfortunately, as I had already disabled the selective suspend. My machine's Windows is already up to date with the most recent versions, I doubt it's a software problem.

Before sending my laptop back, I wanted to figure out if it's the display adapter that could be at fault and if I had to try a different one, what should I look for to make sure it's HP compatible

@samuele-m It's not usually brand dependent, but a better thing to do, would be to take the computer over to the local tech store, have him check a few cables that work and then buy the right one that is compatible or works with your device.

I hope that helps!
