Review on 🔌 Rommisie 4K HDMI Cable (6.6FT, Black) - High Speed, Gold Plated Connectors, Ethernet Audio Return, Video 4K, FullHD1080p 3D - Xbox, Playstation, PC, HDTV Compatible by John Brouillard

I mean it works as written. I don't know if the picture quality is 4k though. Because if my TV doesn't support 4k quality, it won't display 4k, which makes sense. But my TV supports 4k, so when you display something on the TV with this cable, the quality doesn't go up, it stays the same. Also, the cable is thick, making it difficult to bend behind the TV.
