Universal USB cable of a new type will support DisplayPort

Not so long ago on Habré already published the news that the USB cable of the new generation is ready for production. In April, Intel showed the first sketches of a new type of Type-C connectors, and in August, the USB Implementers Forum (USB-IF) agreed and approved the specifications of the new standard.

Now another organization, the Video Electronics Standards Association (VESA), is now adding support for the DisplayPort standard with a new cable. According to VESA, the new USB Type-C cable can be used to work with DisplayPort, with the ability to connect monitors with a resolution of 4K and higher. In addition, the cable can be used to work with data according to the SuperSpeed ​​USB standard (USB 3.1) and supply power (up to 100 W of power).

When creating the appropriate adapters, it becomes possible to use the DisplayPort Alt Mode with existing DisplayPort, HDMI, DVI and VGA monitors. When operating in this mode, SuperSpeed ​​USB lines are reassigned to deliver DisplayPort data, while the remaining USB Type-C lines are used to transfer information over AUX, with support for the HPD (Hot Plug Detection) function.



To work with devices that support the DisplayPort standard, you need a bi-directional conversion cable with USB Type-C and DisplayPort standards. As for the source of media content (video), it can be connected to HDMI, DVI or VGA devices using a new type of cable and an appropriate adapter.

It should be noted that in any mode of operation, the cable still supports any mode of orientation of connectors and the direction of cable connection (i.e., the cable can be connected either side, with any orientation of the connector).



Currently, developers have already announced their readiness to implement support for DisplayPort Alt Mode in new devices, with support for the DisplayPort 1.2a specification (data transfer speeds up to 5.4 Gbit / s per line). Thus, the cable can be used to connect monitors with a resolution of 4096 * 2160 pixels (4K) and 30-bit color display depth. If you use all four lines in DisplayPort Alt Mode, you can also support monitors with a resolution of 5K, with the possibility of simultaneous transfer of USB 2.0 data over reserved USB Type-C pins.
