You won't find anything about USB-C with only one port assignment. You need at least a 2-port like this one: Satechi ST-TCDMMAM (HDMI, 60W, USB Type C, USB A)
Or you can use a Thunderbolt 3 dock if your laptop has one. The bottleneck is the data bandwidth that a single USB-C port can deliver. 4K@60Hz requires about 18 Gps, which is beyond the bandwidth of USB-C 3.1 Gen2. This should then no longer be a problem for future laptops with USB4.
