I had a big problem with this cable. I almost replaced my new TV because I thought the TV was broken. The picture flickered, disappeared and the sound disappeared. The cable just couldn't support 4K HDR. This cable does not offer the 18 Gbit/s required for HDR transmission. It makes me wonder how this company can put a "Certified" sticker on this cable because it's pure junk. Do not be fooled. Do not buy.
