I didn't buy these because I needed them, but rather I wanted to "future proof" my Dolby Atmos System. I have a 4K Samsung UBD-8500 Blu-ray Player plugged into my Denon AVRX-4400H which feeds a Samsung 75" 2021 QN85A Neo 4K Smart QLED TV. These Cables are the latest "standard" and can handle 8K transmission. I connected them direct from the the Blu-ray to the TV as well. Every combination worked flawlessly. I'm ready if I get anything 8K!

The quality of this cable is good and doesn't add too much bulk. I bought four cables to ensure all my devices use higher bandwidth cables. The only device in my house that can take advantage of HDMI 2.1 is my PC. I hooked it up to my RTX 3070 Ti, and it outputs in 4K @ 120hz on my Hisense 65" U78G without problems, and VRR works. I knocked off two stars is because they misrepresented the "Ultra High Speed HDMI® Cable Certification Program" in the production description. The physical product and packaging do not indicate that it's an "Ultra Certified Cable," even though Primecables advertises this certification, there has no way of validating the authenticity. As a result, the production description is misleading. However, I didn't expect much because the price is reasonable and works. In summary, if you want peace of mind and have an authentic HDMI 2.1 cable where you can psychically validate it through the HDMI app, steer away. However, if you want a well-priced cable that works without issues, go for this product.
