Video and Data Bandwidth Optimization: USB 3.2 allocated fixed bandwidth to data or video or, in DP Alt Mode, gave 100% to video. DisplayPort and Thunderbolt 3 are also supported via Alt Mode.īackward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3: USB4 maintains compatibility with previous versions of the USB specification and, thanks to its Thunderbolt 3 foundation, supports TB3 Alt Mode too. Multiple Data and Display Protocols: USB4 supports USB 3.2, PCIe and DisplayPort 1.4a through a technique called protocol tunneling. They can optionally support 40 Gbps (4.8 GB/sec) if they use the shorter 0.8 meter Gen 3 cable. Up to 40Gbps Data Transfer Rate: USB4 devices are required to support 20 Gbps (2.4 GB/sec). The USB4 protocol requires a USB-C to USB-C cable. USB 4 (officially 'USB4' without the space) is an important update, not only for the new capabilities it offers but because it helps to resolve the confusion over USB 3.x naming and, for the most part, it gives users a predictable and consistent experience.

While these cables can be connected between devices, they require an adapter, such as a USB-to-HDMI converter, in order to translate the signals properly into something the output device can interpret and present.
