These cables were purchased to connect to Sony's new 4k HDR OLED TV with the 4k Xfinity DVR. I was disappointed with the picture quality I got from these cables as the picture quality was inferior to what I had previously had with my existing HDMI cables. I ended up replacing those cables with much better Audioquest HDMI cables (I chose their Forest model). The quality of my picture immediately improved significantly. My suggestion if you are looking for high quality HDMI cables for your 4k HDR TV is to avoid these cables as their performance has been questionable in my experience.
