It ONLY works with a USB connection. They give you a nice USB cable, but they don’t tell you the camera will not work without it. I had to find this out by searching online. This is a poor show by Samsung. They should say it straight away in the quick start guide.
I have the same problem. How do I use the monitor's camera? I have connected a USB cable to the USB C port on the PC, but the camera is not recognised there. is there a special driver?
