Review on Monoprice Certified Premium HDMI Cable - 3ft White - 4K@60Hz, HDR, 18Gbps, 28AWG, YUV 4:4:4 by Franz Esquivel

I ordered a pair of these cables because I wanted to use certified 4K cables between my devices, receiver and TV. The Pioneer Elite VSX-LX101TV receiver is a Samsung 82NU8000 Sources include: Xbox One X, Playstation 4 Pro and Nvidia Shield The cables did not transmit signals when the devices were set to 4K. 1080p was ok but not 4K. Replaced the cables with another brand and everything was fine. I am not sure if they are really certified.
