I've got a Spectre x360 15-df1100 that I wish to use with a USB-C screen. Since I already read there were several issues with HP laptops with non-HP USB-C chargers in the past, I first tried charging it through a 30W Apple charger. Since this worked I wasn't worried about the laptop being able to use the 95W charger in the HP e344c screen that I had in mind.
But my surprise couldn't have been any bigger, when I discovered that the laptop is able to use the screen as a display perfectly, however it will not be charged through it. In the menu of the screen I've already enabled performance mode, to ensure power is delivered. Hooking up a Macbook, this device is being charged through the monitor, so the screen is actually delivering power over USB-C. Also I've updated the bios in the Spectre to the version from 23-12-2019.
Any suggestions are much appreciated!

It came with a conventional plug adapter, 90W. Tried the 90W USB-C connection from the display on both ports indeed, both don't work.
Also tried a 30W USB-C charger from a macbook, which worked slow obviously, but it was recognized as a charger and it was charging.

I wish I could tell you its an easy thing. USB-C charging is so far from universal plug and play. HP laptops will now charge from non-HP adapters but not all non-HP adapters. Used to be they would only charge from HP adapters.
