I have had issues with the UHD722 as well, deep color enabled on my LG tv and UHD722 will not let Xbox one Pro output in 4k most outputs dont switch, I have good HDMI cables capable of 40gig, Updated the firmware,
defaulted the TV and 722 re-enabled deep color, it now works except, i cant get ARC to work audio from tv into 722 and out of my G68 any ideas
