Review on CableDirect'S 8K/4K HDMI Cable With AIS Shielding - 15Ft, High Speed & Ethernet Supported For PS5, Xbox, Switch - Designed In Germany by Mike Gruwell

Did what I needed! When I upgraded to a 4K, my Roku kept reporting a 4K HDR display @ 30 Hz instead of 60. And I was getting black screens, lost signal (HDCP negotiating errors I think), etc. Was losing my mind, I knew I had a high speed HDMI cable in the wall already so I was blaming my new receiver that sits between the Roku and TV.but having learned a lesson from a previous issue, decided to replace the cable with a newer, perhaps better one. Turns out the cable I had was 25 ft long, which worked fine for 1080p but was apparently too long for 4K HDR 60. As soon as I booted up with this cable, all of my issues went away. Roku reports 4K HDR @ 60 every time, no HDCP negotiating, even devices powering up via ARC seems to happen a little quicker. Good product, definitely recommend.
