Hello all, I have a 28U like this, unfortunately I can't get it to charge my laptop via usb-c. Usb-c cable transmits the picture but does not charge. Even if I don't transfer a picture, it doesn't charge. Does anyone have any ideas? Laptop is a basic HP Elitebook G8, neither USB-C port seems to charge like this. USB cable is the following: https://www.digitec.ch/de/s1/product/club-3d-usb-c-usb-c-2-m-usb-kabel-21037057
