Dolby Vision 2 HDR is officially rolling out on certain Hisense TV models, with availability starting now on a limited set of devices and expanding to more models in the coming weeks, according to reports from Engadget and TechRadar. The update brings Dolby Vision 2, which includes changes to how HDR content is processed. In particular, Engadget reports that Dolby Vision 2 uses a new scene-by-scene optimization algorithm designed to improve how different parts of a video are rendered. TechRadar similarly describes the rollout as targeted at specific Hisense TVs first, then broadening as the software update reaches additional models. Both outlets frame the release as an official HDR platform update for compatible Hisense sets rather than an unofficial workaround. While TechRadar highlights that it is available on specific models initially and that more units will be added later, both sources agree on the core point that Dolby Vision 2 features a new algorithm intended to better adapt to individual scenes within HDR content.
