VESA, the Video Electronics Standards Association, has announced the release of its latest update to DisplayPort, version 2.1a. This new standard aims to improve display connection by boosting quality and refresh rates, catering to next-generation displays and GPUs.
The update introduces the VESA-certified DP54 UHBR cable specification, replacing the previous DP40 ultra-high-bit-rate (UHBR) cable spec. The DP54 UHBR cable allows for up to four-lane UHBR13.5 link rate support, enabling a maximum throughput of 54 Gbps over a two-meter passive cable.
By doubling the passive cable length for UHBR13.5 GPU-to-display connections, DisplayPort 2.1a provides users with increased flexibility for their gaming or workstation setup. Previously, these connections could only be supported using a DP80 UHBR cable. With the new DP54 cable specification, both UHBR10 and UHBR13.5 sink and source devices can be supported with passive cable lengths of up to two meters. Monitors equipped with UHBR13.5 are capable of driving high-resolution and high-refresh rate combinations, such as 8K2K at 240Hz or 8K4K at 120Hz.
One of the key advantages of the DisplayPort 2.1a update is that it addresses the limitations of the previous DP80 cable. Users are no longer restricted to using a one-meter DP80 cable when connecting UHBR13.5 sink and source devices. This allows for more bandwidth support without the risk of cable length being too short for certain setups, including ultra-wide curved displays.
It is important to note that while the DP40 cable spec is being phased out, existing DP40 cables that have already been shipped are still compatible with the new DP54 cable spec. VESA has conducted extensive testing to ensure that these cables support UHBR13.5 link rates. Additionally, the DP80 UHBR cables certified by VESA continue to support sink and source devices that require UHBR20 link rates.
Overall, the introduction of DisplayPort 2.1a brings significant enhancements to display connections, providing users with improved display quality, higher refresh rates, and greater flexibility in their setup choices. With the increasing demand for next-generation displays and GPUs, this update from VESA is a welcome development in the industry.
