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

I've connected this to my PS4 Pro (no problem) and 4K Roku (problems). Roku posts an HDCP 2.2 bug like it's a job or something. I didn't have this problem with my old HDMI cables, but I couldn't get 4K with them. Roku flashes a lot of black screens and as soon as it goes into screensaver mode, the screen goes black. Again, there was no such problem with the old HDMI, but not with 4K. So I'm not sure if this is 100% cable related or not. But on my PS4 PRO it works fine. I will buy a well known brand and update my review after testing.
