Review on HDMI Cable 4K Ultra HD - 100ft (1 Pack), Nylon Braided HDMI 2.0 Cable: High Speed 18Gbps, 4K@60Hz HDR, 3D, 2160p, 1080p, HDCP 2.2, ARC, HDMI Cables for Monitors and HDTV by Justin Pavelko

Used cables for Create a game room with 55" 4K TVs. My computer runs at 3840 x 2160 at 60Hz, which is what these cables offer. The first cable used failed immediately in the picture. I thought it was a bummer, it was with 1 bad cable. The second and third cables didn't reach 60 Hz and caused serious graphics problems. Finally down to 30Hz and still having crashes and screen tearing while gaming. Went upstairs and grabbed my Amazon main cable and the problem was fixed, the screen runs at 60Hz with no cracks or crashes. So, 3 out of 3 cables are bad. Don't buy this product, it's a waste of money.
