In this mode, Dolby Vision supported TV’s will switch into the correct color space and gamma without the need for end user configuration

  • Dolby Vision Absolute mode: This provides HDR video without tone mapping while preserving color space, video levels and gamma. Master monitor peak brightness is used as a clipping ceiling. Dolby Vision compatible TV is required for Absolute Mode.
