LG 60 SJ8000 LG UBK90 BRP Hi. I am having an issue when turning on the UHD Deep color for certain inputs. On Input one with my BRP I get no input signal or sometimes it flickers on and off. On Input two with my cable box I get picture but no sound. Both TV and BRP support dolby vision HDMI Cables are within 2 years so I assume they are 2.0. 4K works fine, HDR works fine but when I turn the deep color on everything gets wacky. Any Ideas?
