Hi @njsdavis,
Thanks for posting!
Looking at the manual for this specific HP computer, it appears to have a USB-C port that supports both video and charging, so I would expect our USB-C docks to compatible.
You might want to consider our Plugable UD-ULTCDL docking station: https://plugable.com/products/ud-ultcdl/
This dock supports up to three displays via two HDMI ports and one DVI port. The dock provides additional USB ports, Ethernet, and audio, while keeping the host computer charged with up to 60W of power. Please find more details on the product page above and let me know if you have any questions.
I do want to be transparent however and let you know that while we have seen most newer models of HP Spectre x360 15" laptops be compatible with this dock, we have seen varied compatibility. With older models, we’ve had some customers have report success, but others have reported the dock to not function.
We do offer a 30-day no-hassle return policy fulfilled by Amazon (FBA) in case you might have any problems.
Thanks!
Mitchell
