With USB specification 3.2 and the 2x2 mode, the cable can support bidirectional bandwidth of up to 20 Gbps by using two lanes simultaneously with each lane carrying 10 Gbps, thus creating a dual lane operation that can reach up to 20 Gbps. There are four differential high speed lanes – for USB there are two SuperSpeed receiver differential pairs and two SuperSpeed transmitter differential pairs, sometimes called a lane. 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.

Inside the Type-C connector, there are 24 pins that serve a variety of functions that make these configurations possible. Inside Type-C and its SuperSpeed PairsĪ USB Type-C cable connection can act as a USB host, USB device, USB-PD power consumer, USB-PD power supplier, and as a DisplayPort video connection.

In this article, we’ll discuss how DisplayPort protocols operate on Alt Mode over a Type-C cable and how it compares to the operation of a standard DisplayPort cable. This allows users to take advantage of multiple technologies all through a single cable, maximizing efficiency. One of Type-C’s features that allows for its flexibility is Alt Mode, which can optionally support non-USB signals including DisplayPort (DP) technology. I'm pretty sure that you could power up an original Macintosh or Apple IIe and it would still function in this modern age without appearing that slow.In the world of cables, USB Type-C is considered to be the most powerful and versatile connector type to date. It used to be something that Apple was proud of, that their computers lasted much longer than any of their competitors. I have to say I'm pretty disgusted with Apple's attitude of '2011? Oooh, that's old, we don't support that, you should buy a new laptop!!'. What do I do with my beloved laptop now? I'd love to get it repaired but (apparently) the only people with sufficient skill and technology are Apple engineers themselves and I can't justify spending the price of a brand new Wintel laptop just to repair a faulty GPU. I had it re-flowed by a (non-Apple) repair centre (Apple just said 'it's old, we're not interested') but the fault returned within a couple of months. I was a huge fan of Apple until my 2011 MacBook Pro developed a GPU fault last year.
