VESA to Develop DP80LL Ultra-High-Bit-Rate (UHBR) Cables for 80Gbps DisplayPort; NVIDIA Is Helping
The Video Electronics Standards Association (VESA) announced its plans to introduce new DP80LL (“low loss”) ultra-high-bit-rate (UHBR) cables, supporting up to four-lane UHBR20 link rates with a maximum throughput of 80 Gbps. These active cables will extend up to three meters in length, significantly increasing the connection range for DisplayPort devices. The DP80LL cables will be a key feature of DisplayPort version 2.1b, set to be released in spring 2025, offering up to three times the cable length for UHBR20 connections compared to current DP80 passive cables. VESA-certified DP80LL cables are expected to reach the market in the coming months.
NVIDIA has been collaborating with VESA to ensure compatibility and performance between its GPUs and the upcoming DisplayPort 2.1b technologies, including UHBR20 functionality with DP80LL cables. This partnership aims to provide enhanced bandwidth and flexibility for gaming, content creation and professional workflows.
DisplayPort 2.1’s high bandwidth enables support for extremely high video resolutions and offers additional features, including multi-stream transport (MST), which allows users to connect multiple displays through a single cable. This feature is ideal for competitive gaming, content creation and office workstation setups.
DisplayPort also supports multiple connector formats, including standard full-size and mini DisplayPort cables, as well as USB Type-C through DisplayPort Alt Mode. This allows video, data transmission and device charging through a single cable. DisplayPort can also function as a tunneled protocol through Intel’s Thunderbolt and USB4 interfaces.
The use of DisplayPort’s common PHY/IP with the USB connector simplifies integration into chip designs for electronic devices. It has become the standard interface for embedded applications, including laptops, notebooks and premium tablets, as well as automotive video systems. DisplayPort provides functional safety and secure integrity for automotive displays, supporting up to 16 display regions of interest.
As an open standard developed by VESA, DisplayPort benefits from the contributions of over 340 member companies, ensuring its continued evolution and widespread adoption across industries.
