The Video Electronics Standards Association (VESA) revealed significant updates at CES 2024, introducing DisplayPort 2.1a and Automotive Extension Services protocols. DisplayPort 2.1a replaces the DP40 cable specification with the new DP54 UHBR cable spec, doubling the passive cable length for UHBR13.5 GPU-to-display connections. This innovation, supporting up to four-lane UHBR13.5 link rates (54 Gbps throughput), enhances flexibility in gaming and workstation setups.

Monitors enabled with UHBR13.5 can achieve resolutions like 8K2K at 240Hz or 8K4K at 120Hz over four lanes. Existing DP40 cables are confirmed by VESA to comply with DP54, ensuring a seamless transition for consumers. James Choate, compliance program manager for VESA, emphasized that this update provides purpose-built UHBR13.5 cables for longer passive connections, offering consumers greater bandwidth support without length limitations. In a significant move towards automotive safety and security, VESA announced the Automotive Extension Services protocol for DisplayPort 2.1a and eDP 1.5a. This protocol introduces safety and security features, establishing a standard for functional safety, authenticity, and integrity verification of automotive displays. It ensures ISO 26262 ASIL-D compliance for electronic safety integrity. The Automotive Extension protocol includes a functional safety profile for the main data path and metadata, utilizing high-safety-rated CRC polynomial mathematical signatures for every frame. This prevents dropped or repeated frames, crucial for capturing critical events. Additional features include safety profiles for the DisplayPort Aux channel, security authentication and integrity checking on the data path, and encryption of the DisplayPort Aux channel. VESA's Roland Wooster, from Intel Corporation and Chair of the Display Performance Metrics Workgroup, demonstrated a UHB 20 setup using DisplayPort 2.1. This involved real-time demos with Synaptics and Realtek hubs, showcasing multiple monitors connected through HBR3 and UHB cables. Different performance standards, including UHB 10, UHB 13.5, and compression ratios, were discussed for optimal display experiences. The focus shifts to a DP 2.1 demo featuring UHB 20, a real-time demonstration of the Synaptics and RealTek hubs using DP 2.1 technology. Different performance standards, such as UHB 10, UHB 13.5, and compression techniques like Display Stream Compression (DSC), are explained. The conversation touches upon the integration of DP80 links over USB-C Thunderbolt ports, potentially offering an 80 Gbps link for displays and data transfer. The video highlights the practical use of DSC to achieve higher resolutions and frame rates with a visually lossless compression ratio of 3:1. The discussion also covers the capabilities of Intel-based platforms, the number of displays they can drive, and the potential use of DP80 cables for high-speed data transfer. The practical aspects of connecting multiple devices, including power delivery, are explored. The demo emphasized the potential of DisplayPort 2.1 for high-resolution displays and higher frame rates, thanks to the efficiency of 3:1 compression ratios in Display Stream Compression (DSC). The cables used were Type-C on both ends, capable of delivering up to 80 Gbps, providing both power and data bidirectionally. The discussion delved into practical applications, such as video editing workstations, where the 80 Gbps link could enhance performance and support multiple displays. The system featured an AMD 7900 XT GPU supporting a 13.5 Gbps full-size DP output, connected to a Dell 6K 60Hz display, demonstrating real-time 6K video editing. VESA encourages electronics, display, and automotive manufacturers to join efforts in shaping the Automotive Extension Services protocol. The VESA Automotive Extension Working Group is open to all VESA members, and interested companies can apply for membership on the VESA website.
