This review will be short and sweet. I've had a lot of feedback that these cables can't handle 4K HDR or support 4:4:4 chroma at 60Hz. While I can't speak to other users' configurations, I can confirm the following: Using this cable on a Samsung KS8500, I can confirm that this cable supports: UHD 4K HDR Content4K 30Hz 4:4:44K 60Hz 4:4 :4I have also enclosed a color test photo. The bottom two lines are perfectly visible with this cable.
