People with AMD Ryzen 6000 Series CPUs and Intel Arc GPUs will benefit from this, but not NVIDIA product owners.

VESA released the DisplayPort 2.1 specification today. Typically when an industry group announces a new standard, it takes months or even years for products supporting the spec to be available to consumers. But DisplayPort 2.1 products are already available; in fact, you may already own some. VESA also declared today that any product that was already DisplayPort 2.0-certified before today's announcement is now DisplayPort 2.1-certified, too.
"VESA has been working closely with member companies to ensure that products supporting DisplayPort 2.0 would actually meet the newer, more demanding DisplayPort 2.1 spec," the announcement from VESA, which also makes DisplayHDR, AdaptiveSync/MediaSync, Clear MR, and monitor-mounting specs, said.
"Due to this effort, all previously certified DisplayPort 2.0 products including UHBR (Ultra-high Bit Rate) capable products—whether GPUs, docking station chips, monitor scalar chips, PHY repeater chips, such as re-timers, or DP40 / DP80 cables. (including both passive and active and using full-size DisplayPort, Mini DisplayPort, or USB Type-C connectors)—have already been certified to the stricter DisplayPort 2.1 spec," VESA also said.
Just like that, DisplayPort 2.0 products have been bumped up a tick. However, there aren't many DisplayPort 2.0 products to speak of right now. DisplayPort 2.0 products were initially expected in 2019 but, due to the COVID-19 pandemic hurting testing capabilities, didn't start becoming available until this year.
AMD Ryzen 6000 is DisplayPort 2.0-certified, as are some MediaTek and RealTek chipsets, DisplayPort cables, and docks, but that's about it. We don't know of any DisplayPort 2.0 monitors readily available for purchase in the US. Intel's Arc graphics cards, including the Intel Arc A770 and A750, support DisplayPort 2.0, but Nvidia's latest GPUs, the RTX 4090 and 4080, and AMD's latest cards, the Radeon RX 6000-series, do not.
