New Type Universal USB Cable Will Support DisplayPort

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

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

When creating the appropriate adapters, it becomes possible to use DisplayPort Alt Mode with existing DisplayPort, HDMI, DVI, and VGA monitors. When operating in this mode, SuperSpeed ​​USB lines are reassigned for DisplayPort data delivery, the remaining USB Type-C lines are used to transmit information via 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 the corresponding adapter.

It should be noted that in any mode of operation, the cable still supports any mode of orientation of the 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 DisplayPort Alt Mode support in new devices, with support for DisplayPort 1.2a specification (data transfer rate up to 5.4 Gb / s per line). Thus, the cable can be used to connect monitors with a resolution of 4096 * 2160 pixels (4K) and a 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 ability to simultaneously transfer USB 2.0 data through the reserved USB Type-C pins.
