Up to six peripherals may be supported by one connector through various topologies. Thunderbolt combines PCI Express (PCIe) and DisplayPort (DP) into two serial signals, and additionally provides DC power, all in one cable. It was initially marketed under the name Light Peak, and first sold as part of an end-user product on 24 February 2011.

It has been developed by Intel, in collaboration with Apple. Thunderbolt is the brand name of a hardware interface for the connection of external peripherals to a computer. HS1TX(P) of the source is connected to HS1RX(P) of the sink.

The cable is actually a crossover cable, it swaps all receive and transmit lanes e.g. This is the pinout for both sides of the connector, source side and sink side.

I have successfully tried the monitor on an Apple MacBook and it look great. The USB 3.1 Type-C port must support DP Alternate (Alt) Mode or DisplayPort and you can normally see the DP-logo next to the port if this is the case. There are four differential high speed lanes – for USB there are two. USB Type-C cables include four pairs of SuperSpeed wires, which can be used for high speed data transfer or can be configured as Alt Mode to support third party protocols. Specifically, the DisplayPort video protocol can be configured using Alt Mode, which can be carried out over the USB Type-C standard.
