infinnet 8K HDMI 2.1 Cable, Ultra High Speed HDMI Cable 4K HD 120Hz 144Hz 2K 240Hz Gaming HDMI Cable 48Gbps Version 2.1 Certified, eARC HDCP 2.3 2.2 HDR Dolby Vision Atmos HDMI Cable, 1m (3 feet)

Feels durable, and the cable is superb compared to some what of the other companies offer, in terms of continuity of the features of the HDMI cable, the signal integrity, and the overall quality. Sure, you could buy cables that MAY be cheaper elsewhere, but the quality is likely to not be good with cheaper cables.Verdict: Don't look elsewhere. Buy this one with peace of mind

Bought this HDMI cable for my 75" Samsung QNED 8K TV as an extra input cable.This ultra high speed hdmi cable delivers great colors, contrast, sharpness and detail, overall better image quality compare with other HDMI 2.1 cables I have.Very happy with this purchase. Highly recommended.

this is advertised as a 240hz 2k hdmi 2.1 cable i have now been trying to get it to work on 240hz 2k i can very much do run it i had a dpi cable before but my dpi port on my monitor broke so i had to get an hdmi that’s supports 240hz let me down for $50 i can only use 120hz

All HDMI cables are definitely NOT equal. Skeptical of marketing techniques, I purchased three Infinnet ultra high speed HDMI 2.1 cables. Two 1m, and one 3m cable. The boxes all had the UHD certified hologram on them. I downloaded the phone app and verified that the boxes were certified. The cable jacket is also printed with “ultra high speed HDMI cable”. But, I also have a marantz SR 6015 receiver which measures cable speed and volume in gigabytes per second. (GBPS) After testing, all three cables passed the 8K-40 GBPS test. I have tested other brands that make the claim but do not hold up under the test. This is the real deal… WORD OF CAUTION; Cable placement next to power cords will interfere with performance! I experienced this during my test! Be forewarned! I did not receive any compensation for this review. Just wanting to help others out!

As per the specification, my rtx 3070 should work at 4k 120hz for HDMI output. But it could only do 4K 30hz with HDR or 4K 60hz with SDR.From the forums I understand that rtx 3000 cards are picky, I tried several HDMI cables announced to be 2.1, some cables worked but with intermittency. Rtx 3000 cards are even more picky than I thought.infinnet HDMI cables is of high quality, everything is working flawlessly even at 4k 120hz.
