It's all pretty simple, with just a USB Type-C cable on one end, HDMI on the other, but there are a couple of drawbacks. It supports the older HDMI 1.4b spec instead of the newer HDMI 2.0b. What that means for you is that while 4K video, 3D, HDMI-CEC and Audio Return Channel are all supported, it won't be quite enough to send the newest Ultra HD 4K video with HDR. That's probably not an issue if you're just trying to play a video or two from your phone, but it's good to know.
