HP Spectre X360 USB-C monitor

[ERS22]

Hi,

I am using a HP Spectre X360 15-bl1XX and I recently purchased the Dell u3421we ultrawide USB-C monitor. From my understanding, all I needed was a single usb-c cable to go from the monitor to my laptop to provide both power and video. However when I plug just the usb-c cable in, my laptop receives power but does not output to the monitor. This forces me to resort to plugging in a HDMI cable.

Is it possible to have a single cable setup to work on my computer model?

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:

• Have you checked with a different display or monitor?
• Have you tried using a USB hub?

Keep me posted for further assistance.

I have connected my Galaxy S10 with Dex to the monitor and that has worked with one cable no problems. I have not tried a USB Hub as the idea of purchasing this monitor was that is already had USB ports for USB pass through

Thank you for posting back. 

The Samsung Dex works differently than the actual USB-C port. 

You may try with HDMI port to output Video signal to your monitor. Click here: https://support.hp.com/in-en/document/c04641829 to know more about Using Two or More Monitors with One Computer (Windows 10, 😎

Since my last message, I have tried connecting my monitor to various laptops via usb c and it all works by connecting the one cable. I think what I am trying to find out is whether my laptop in particular has DP Alt Mode. So far I can get data, power, video and sounds through just one usb c cable on other laptops but not mine.
