Review on 🔴 iVANKY 4K HDMI Cable 3.3 ft - High Speed 18Gbps, 4K HDR, 3D, 2160P - Ethernet, Braided Cord - Audio Return(ARC) Compatible UHD TV, Blu-ray, PS4, PS3, PC, Projector - RED by Chris Horton

I bought a new Samsung 4k TV with HDMI cable troubleshooting. I was shocked that he suggested replacing the HDMI cable I was using with a "Certified HDMI Cable". I thought all HDMI cables were the same. I used the HDMI cable that came with my Xfinity cable. So I switched the HDMI cable to this, ran the troubleshooter again, and TADA! I definitely see a difference in picture and sound quality. I'm currently using an older stereo surround system and the sound is getting richer and richer. I bought more for other components I use with the receiver.
