## Customer Reviews

### ⭐⭐⭐⭐⭐ Flexible and works for 4k 120Hz HDR gaming
*by E***H on April 3, 2025*

This hybrid fiber optic cable works well. I’m using it to connect my PC to my TV for gaming. I tried a 20ft passive HDMI cable, but it was so thick and stiff that I was afraid of damaging the ports on my GPU and TV due to strain. This cable is much thinner and more flexible, so I don’t have to worry about that. I was still careful when installing to not bend it too much since it has glass inside. It meets the HDMI 2.1 standard, and I can play PC games on my TV at 4k, 120 Hz, and HDR with no issues.

### ⭐⭐⭐⭐⭐ Works great
*by C***Y on June 7, 2025*

Works great for security cameras

### ⭐⭐⭐⭐⭐ Almost returned my LG C4 until I tried these.
*by K***N on May 29, 2025*

These cable saved the LG C4 which I'm using as PC monitor. Initially I was constantly getting screen flicker/blinking which I'm not able to resolve with two different 8K HMDI cable brands from Amazon. After buying this fiber optic HDMI the flickering instantly went away. These cables delivered smooth, brilliant, 120hz HDR OLED PC gaming. Mission accomplished.
