I installed a wall plate with HDMI and other stuff right behind my receiver and was able to connect everything I needed. I was even able to get them to work at 4k @ 60Hz and 1440/1080 @ 60 and 120Hz with lots of jacks and stuff. I haven't tried HDR but they pass CEC and ARK. They're a bit stiff, but that's to be expected with cables this THICK. I love the additional cable management hardware that comes with it. I'm not using it for these cables but will be using it for other things in my setup.
