Review on PowerBear 8K HDMI Cable 3 ft: High-Speed Connectivity and Reliability! by Scott Carlile

After purchasing this cable and not getting better results, I spoke to TV vendors and they claim that regular HDMI cables work just as well and there isn't much of a difference between cheap and expensive cables are cables. . If your source is bad, your TV signal will be bad. (xfinity, directv, dish, etc. do not broadcast in UHD or 4k). So your picture will still be just as bad. You will only get a 4k quality picture if it is broadcast in 4k or UHD. Currently, you can only get this from streaming services or Blu-ray discs. I'm not saying this cable is bad, but regular cables give the same picture quality.
