Hi, I can confirm this. I am on Software Version J1127 and when watching Dolby Vision content, no matter what settings I try, the backlight option is always greyed out. It would be amazing if Hisense could fix this.Can owners of the Q8600 please confirm if the backlight option is grayed out for you when viewing Dolby Vision content?
Or are you able to change it?
Have spoken to Hisense and trying to get them to look into this.
