have to check to enable the dolby vision option in the HDR settings dropdown, then uncheck to disable it, by default it's turned on but the box isnt checked. Took me a while to figure that out even knowing the issue was relating to dolby vision setting
i checked every single settings on the tv (lg c2) and there is no dolby vision menu or option, even if you set filmmaker preset it remains on, the only way to fix it to me is to disable hdr in windows 11 hdr menu...
