Xbox Series X/S already supports Dolby Vision games
Microsoft is currently working closely with developers to provide the tools needed to make full use of Dolby Vision in games to ensure that the number of games that support Dolby Vision continues to grow. Developers can do this through the built-in functions of the Xbox platform, or they can choose to apply the technology directly to the game engine.
If you want to get the best Dolby Vision gaming experience, you need a TV that supports Dolby Vision and turns on the relevant settings. At that time, games that support Dolby Vision will be automatically mapped. Through Dolby Vision, the brightness, color, contrast, and detail of the game can be raised to a new level. It is also compatible with Xbox Series X/S next-generation features, such as ray tracing, automatic low latency mode (ALLM), variable refresh rate (VRR), and 120FPS rate, depending on the TV’s capabilities.
