Review on 🔌 50ft DELONG 8K Fiber HDMI Cable, HDMI 2.1 Fiber Optic Cable for 8K@60Hz & 4K@120Hz, 48Gbps, eARC Compatibility - PS5, Xbox, RTX 3080 3090, Roku, 8K TV Compatible by Jessica Breaux

Won't connect. Tried on many devices. Oh yes, that goes in the right direction :) Source at Source (example: PC) and Display on Display (example: TV screen) Well, at first it seemed to work a bit on some devices, then not on others, but testing was inconsistent and briefly worked on others before quitting. Tried this for some time and no results with any devices/displays. Conclusion: We were the few who received a defective product. Request a refund or replacement. and how do i send it back? I see no way back. (UPDATED) We have a spare and it works great :)
