VESA updates DisplayPort to support 4-meter cable length and also one for automotive

Video Electronics Standards Association (VESA), who owns and updates DisplayPort specs has announced two new updates separately for gaming and automotive at CES 2024. 1. Gaming: VESA published the latest update to DisplayPort, version 2.1a replacing VESA certified DP40 ultra-high-bit-rate (UHBR) cable specification with a new VESA certified DP54 UHBR cable spec to enable up to four-lane UHBR13.5 link rate support (a maximum throughput of 54 Gbps) over a two-meter passive cable. This enables doubling passive cable length for UHBR13.5 GPU-to-display connections which previously could only be supported through a DP80 UHBR cable. This will benefit consumer with greater flexibility in their gaming or workstation setup. Monitors enabled with UHBR13.5 can drive resolution/refresh rate combinations as high as 8K2K at 240Hz or 8K4K at 120Hz over four lanes. While VESA is eliminating the DP40 cable spec, existing DP40 cables that have been shipped to date have been confirmed by VESA through rigorous testing to be compliant with the DP54 cable spec and support UHBR13.5 link rates. Sink and source devices supporting UHBR20 link rates (a maximum throughput of 80 Gbps using all four lanes) continue to be supported by VESA certified DP80 UHBR cables. The new DP54 cable specification enables support of both UHBR10 and UHBR13.5 sink and source devices with passive cable lengths o...
