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 Brooke Stolen

This cable looks and packs like a reference quality audio cable, but I sent the replacement cable back right after the original cable and that Replacement cables could not capture and hold a 4K 60Hz image. My LG 4K monitor would intermittently disappear and then produce a new image, blanking the screen each time, while my Samsung 4K TV would not display any images at all. The symptoms on the LG monitor were the same for both cables, indicating a design flaw and not a manufacturing defect.
