USB-C HDMI hubs

USB-C hubs with an HDMI output to show the MacBook or iPad screen on a monitor or a TV, in 4K as advertised depending on the model. They also add USB-A ports, a Power Delivery charging port, a card reader or an Ethernet socket, from 3-in-1 to 11-in-1. A MacBook with a base M1, M2 or M3 chip supports only one external display.
