lg 27md5klb webcam not found Using cable that came with monitor to connect to macbook pro (2019) running 10.15.1. The built-in usb webcam is not found by the mac. 

Do I need to also connect the usb from the monitor to the macbook pro? I hope not, because the mbp only has usb-c ports which means I need to buy an adapter.
Contacted LG. Faulty monitor. Getting it serviced. If anyone is curious, they pay for shipping, but it takes 10 business days to fix. Will report back.
