I received a very cheap HDMI cable (no name, no indication of high-speed or 4K), a German power cable and a USB cable in the box. Unfortunately, the Swiss power cable was also missing from my delivery. I recommend buying a CH cable and a high-quality DP cable or a high-quality 4k HDMI cable. I feel that the device works better via the DP cable. I have not tested the USB-C connection. LG Roger
