Displayport 1.2 over USB C doesn't work.

HP Recommended
HP Pavilion 15cs0061cl
Microsoft Windows 10 (64-bit)

Hello,   I am trying to connect a monitor to my Pavilion laptop using a j5 create USB-C to DP cable.  The specs for this computer state that it is DP 1.2 capable but I don't think that the port is configured correctly.  I get an error when connecting that say the display may not function.  The monitor is a 1080p monitor that works just fine.  Is there a way to enable DP alt. mode for the USB-C port in the registry?

Here are the listed spec for the HP Pavilion 15cs0061cl

1 USB 3.1 Type-C™ Gen 1 (Data Transfer up to 5 Gb/s, Power Delivery, DisplayPort™ 1.2, HP Sleep and Charge); 2 USB 3.1 Gen 1 (1 HP Sleep and Charge); 1 HDMI 1.4; 1 RJ-45; 1 headphone/microphone combo

Thanks in advance for the help!!

Hello Praveenbv,  Thanks for taking the time to assist me.

 

The BIOS update utility gives a warning that it is not compatible, but the onboard HP support assistant did update the BIOS last June.  In the Bios, I can find no option to configure the USB-c port.

 

I already have the Intel driver assistant and it warns not to install other than the factory recommended drivers for the UHD 620 card.  Would it be okay to try the different drivers?

 

Windows is up to date on the latest 20H2 version and has no other problems.

 

Thank you for the help!

@Praveenbv  Hello and thanks again!  The Intel support assistant runs on my notebook but gives message (see below) regarding customized HP graphics drivers.  Everything is up to date through the HP and Intel support assistants

 

"A customized computer manufacturer driver is installed on your computer. The Intel Driver & Support Assistant is not able to update the driver. Installing a generic Intel driver instead of the customized computer manufacturer driver may cause technical issues. Contact Hewlett-Packard (HP) for the latest driver for your computer."

 

^^This is from the Intel support assistant.

Do you know if there is any possible registry edit to give function to enable the DP Alt. mode over USB-C?

Specifications for this notebook it should work without problem.  The cable and monitor work with a Dell laptop so I know that they function.

 

Thanks again for your help!!

@Hähnchen, Welcome to the HP Support Community!

 

We have done the basic troubleshooting as per the document and the notebook needs to checked taking remote access so that get to know it's a hardware or software issue.

 

I'd suggest you contact HP in your region regarding the service options for your computer or HP Chat Support Team.

 

             

Hope this helps! Keep me posted.
