Disable Dolby Vision/Open HDR options in Roku TV TCL R655 TV

Does anyone know the secret menu code to disable Dolby Vision/Open HDR options in Roku TV TCL R655 TV?  The previous secret codes for the 4 series don’t appear to work.

      The only way I knew how to get around it was disabling Dolby Vision in our Xbox Series X (TV settings on Xbox dashboard) and watch streaming services thru that.

      Also turn off your Action Smoothing and Action Clarity off on whatever picture mode you use. That seemed to help us when watching regular cable. Looks like normal 1080p upscaled to 4K. Not looking like the weird blur/judder **bleep** of Dolby Vision. 

  • Agreed, I turned all smoothing off. And I think Dolby is still active.
