Hi guys. I just bought this monitor. From the serial number it's not a "U" and yet I have a USB port. Right now my MB Air is connected via USB -C to the monitor's HDMI port. But I read that I could use the USB-C port instead for dat, power and video and that this will also power the hub at the back of the monitor so I can connect my external keyboard for ex. I tried with a few USB-C to USB-C cables I had lying around and it didn't work. I'm hoping it's the cables. Can you confirm that this will work if I use the correct cables? Thanks in advance for your help. T
