Maybe I am doing it wrong. On Windows 10 MPC-BE with madVR would pass HDR/DV meta data through to the display. So you would leave HDR OFF on Windows and a video file that was Dolby Vision or HDR started playing, the tv/display would change to HDR and or Dolby Vision mode
On mac OS I have tried all possible combinations available. mac OS HDR off HDR on 30hz 60hz
Here is what Media Info says about some of the MKV files I’ve tried
For me there isn’t any indication Infuse is rendering the video in DV. The displays Dolby Vision mode is never triggered and nothing within the Infuse video window provides any additional insight.
