I have used this cable as the only connection between my 2019 15" MacBook Pro and the Dell U3219Q monitor with no problems. The monitor puts out 90W of power to charge my laptop. The cable worked fine until the end of October when it started having connectivity issues.I am very careful with all my devices but I plug and unplug the cable from my laptop every workday, I don't leave it plugged in overnight.the display started to work stuck, it took 5-6 attempts to recognize the laptop. I swapped the ports on the laptop and it worked for a couple of weeks, then the behavior returned. Now I've swapped the cable to fix the problem. I' I'm really surprised. The cable seems to be very well made. Not quite sure what happened.
