Bests & Worsts Reviews from Amazon

I really don't understand all the good reviews on these. I purchased due to all the good reviews. I wanted to replace my old HDMI cables with something more updated. Was very excited because price was fantastic. They arrived on time and in perfect condition. Very nice looking cables. Seems well made. I went ahead and swapped out the old for these new cables and put my entertainment center back together and couldn't wait to see the big improvement. What?? Image quality went in the toilet. Tried Cable TV and 4K Bluray. Made the image look like it was missing colors and almost posterized. Went into TV and 4k player settings and all was as it is supposed to be. Tried adjusting color, etc. No improvement. Cable TV had Return Of The Jedi on so I attempted to adjust to no avail. Turned everything off, removed these BlueRigger Rugged High Speed HDMI 2.0 Cables, and put my old cables on. Turned TV and Bluray back on and image was fantastic again. So - I don't know why the old cables are so much better than these. After some web-resesarch I think I'm going to go with AudioQuest Pearls or Forest cables. They are really pricey but what I've read there is a HUGE difference in image quality over cheap cables. Sorry BlueRigger for the negative review.
