DisplayPort 2.0 Bring Alt Mode to USB4 and USB-C devices


DisplayPort 2.0 Alt Mode supports all the capabilities of DisplayPort 2.0 through the USB Type-C connector, this includes beyond 8K high resolution and high refresh rates along with USB data delivery.

DisplayPort 2.0 is the only Alt Mode video transmission commonly used in the industry and used by most video sources using the USB Type-C connector today. It enables the highest possible display output, combined with the high-speed data transfer and power delivery functions of USB Type-C.

VESA (Video Electronics Standards Association) has been announced that it’s released version 2.0 of the DisplayPort Alt Mode (Alternate Mode). With the DisplayPort 2.0 Alt Mode, the USB-C connector can achieve up to 80Gbps of DisplayPort video data utilizing all four high-speed lanes in the cable, and up to 40Gbps with simultaneous SuperSpeed USB data delivery. The first product of DisplayPort 2.0 will be released in the market in 2021.

DisplayPort 2.0 was announced in June 2019, providing high data bandwidth performance up to 3X as compared to the previous version of DisplayPort 1.4a. It has capabilities to future-proof performance requirements of the display. This will include 8K high resolutions, high refresh rates, and High Dynamic Range (HDR).

The advantage of DisplayPort 2.0 is it supports both native DisplayPort connector and USB Type-C connector, which supports audio and video signals through DisplayPort 2.0 Alt Mode. VESA also claims DisplayPort 2.0 is compatible with DisplayPort 1.4a.

Maximize the performance enabled by DisplayPort 2.0 through both native DisplayPort connector and USB-C connector via DisplayPort Alt Mode. USB-C allows you a single connector for USB data, video data, and power. USB-C requires a single USB Data, Video, and Power connector. When SuperSpeed USB data and video are required simultaneously, the dramatically improved data levels provided by DisplayPort 2.0 allow users the ability to provide both power and SuperSpeed USB data at the same time as super-high-resolution video.

DisplayPort 2.0 increased the bandwidth of video performance over a USB-C connector to simultaneously gain high-speed USB data transfer without losing display performance. DisplayPort 2.0 takes advantage of the Thunderbolt 3 interface to maintain the flexibility of the DisplayPort protocol to boost the data bandwidth.

USB Type-C is a popular connection in notebooks and smartphone solutions. With the latest DisplayPort Alt Mode 2.0 standard, USB Type-C also provides convincing single-connector options for charging, entertainment, AR/VR HMDs and advanced HDR displays integrating 80Gbps of video bandwidth and other essential DisplayPort 2.0 capabilities with USB data transfer and power delivery, “said Syed Athar Hussain, VESA vice president, and senior fellow display domain manager.
