https://wccftech.com/ps5-vrr-support-to-be-added-in-future-software-update-sony-confirms/ > Owners of HDMI 2.1 equipped televisions couldn't have been happy to learn that PS5 VRR support is not currently available at launch, despite Sony's next-generation console technically supporting the HDMI 2.1 specification. This is even more of a disappointment because Microsoft has supported Variable Refresh Rate since the Xbox One X, which launched three years ago. > Wccftech readers are very familiar with the technology, first pioneered by NVIDIA with G-SYNC gaming monitors and later by AMD with FreeSync. The DisplayPort spec has included Adaptive-Sync since 2014 and now, at last, the latest HDMI 2.1 spec enabled it as well.
