Have you got a USB-hub?
Maybe your monitor has a usb in and some usb out?
If so try to connect that way.
It sounds crazy but it is often easier to get it to work with a slower port than the fast ports in a modern PC.
I got a fairly new Lenovo Yoga, and things does not work connected directly. But I use a Lenovo thundebolt 4 hub for two secondary 4K monitors and other, and if I attach the cable to that, things work. And both the pc and hub's ports are usb 3.0
