Hi I use a USB-C to display port cable to connect my laptop (via USB-C) to the monitor (via display port), and the screen went blank. I did set the monitor input to be displayport. Can somebody help? Thanks.

Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Is this first time you're trying to set up USB-C displaying settings?
• What is the product number of your device? Use this link to find it: http://support.hp.com/us-en/document/c03754824

After reading your post, I did go through the Product specifications of your product and found that you have USB 3.1 Type-C™ Gen 1 (Data Transfer Only, 5 Gb/s signaling rate)

Hope this helps! Keep me posted for further assistance.

Hi

Thanks for your information.

You mention "data transfer only". Does that mean this USB-C port won't provide the signal video output, and therefore can not used to connect with a monitor?

Hi I just do some research in the internet and find out that USB 3.2 Type-C gen 1 can provide the video support.

So I suspect this port in my laptop s dysfunctional.  Is there an easy way to test it, something like connecting with an external hard drivers to do a test? My warranty will be expired next month, so I would like to send it back for a repair if needed. Your help will be greatly appreciated.

Thank you for posting back. 

To get the answer to this question, the USB 3.1 Type-C™ Gen 1 port on your computer will not output video signal it's only for high speed data transfer.
