Review on ATZEBE 50ft Fiber Optic HDMI Cable - 4K@60Hz, HDR, Dolby Vision, HDCP2.2, ARC, 3D - High Speed 18Gbps, Slim & Flexible HDMI Fiber Optic Cable by David Skyline

My projector is connected to the receiver with a 35ft HDMI cable. It works fine with 1080p video. I recently upgraded to a 4k projector but can no longer watch movies! I know it's definitely a problem with the HDMI cable. Projector support recommended a fiber optic HDMI cable priced at $175, which is overpriced. Then I tried using an HDMI extender with my old cable. I can watch movies with an HDMI extender, but I can't see the Blu-ray player's home screen. I need to buy a high quality HDMI cable! I was a bit puzzled about this cable before purchasing it as the product description does not clearly state that this cable is HDCP 2.2 compliant. The seller responded quickly and confirmed HDCP 2.2 compliance, so I ordered a 50ft cable. Received it today and hooked it up straight away. WOW! Everything works! With the HDMI extender I can only see 4k @ 24Hz, but now it shows 4k video @ 60Hz (although I can't see the difference with the naked eye)! Now I can watch 4k videos without an HDMI extender! And the Bluray player's home screen is displayed normally! I no longer need an HDMI extender. The cable is very flexible and I think it's a bit stronger than another HDMI fiber optic cable I borrowed from a friend. It is thinner than the old HDMI cable because it is fiber optic cable. I still have the problem, but I don't think it's the cable. When I connect an HDMI fiber optic cable to the HDMI port on the wall plate, 4k video displays normally when playing a disc, but I still cannot see the player's home screen even when using an HDMI extender. I've searched the internet and found that many people have the same problem. I believe this is caused by HDMI Keystone as it is HDMI version 1.4. I need to bypass the HDMI port on the wall plate, extend the cable from the wall and plug it directly into my receiver. If you play 4k movies on a device connected with an HDMI cable longer than 25 feet, I recommend you to buy this HDMI fiber optic cable. It works (again, my cable is 50 feet) and it's half or 1/4 the price of similar products sold at Revain.
