TISOFU [Ultra Certified] 8K HDMI Cable 6FT: HDMI 2.1 Cables 48Gbps High Speed Premium Braided Cord 8K@60Hz 4K@120Hz 4K@144Hz HDCP 2.2&2.3 CL3 ARC eARC for HD/HDR/HDTV

Ive been burned so many times with HDMI cables, so I was pretty leery about this one. The QR code and hologram can only be read by the HDMI Certification app. Your phone camera will NOT work. It took me at least 10 tries to get the app to scan the codes, and I could only get it to work on 2 out of 3 packages, but yes, those do appear to be legitimately certified. So far it works fine, but time will tell if it continues to work with my KVM switchbox. The cable this is replacing worked about 99.9% of the time, but would drop out completely 2 or 3 times per day - which was super annoying. I sure hope this one is reliable. If not, Ill check back and excoriate TISOFU for selling crap like everyone else.

Product works great so far. Exactly as stated in the description. Fast shipping!

Trying to get eArc to work on Sonos Arc and this did it with a Samsung QN90A. Not sure how but it wasn’t working and now it is!

Cables are perfect length, sturdy, and working well

Actual certified cable. Works as expected.

Works great. Made a noticeable difference in improved picture quality.

Nothing just haven’t had time to complete everything

HDMI cord works fine and has improved TV sound.

This cable worked after several others did not.

I have tried plenty of HDMI cables, and of them all, this is the one that works the absolute best. High powered and right length, I would recommend this product to anyone.
