‘All HDMI cables are the same’ blah blah blah. Going to put a stop to all these bullsh*t misinformation and comments plastered across some of the other posts.
Now, if you want some decent quality HDMI CERTIFIED 2.1 cables at a GREAT price, get yourself some of these KabelDirekt cables. These cables are up these with the likes of Zeskit and other well known brands. These cables are certified for 4K @ 120Hz. Or else, pick up one of those cheapie uncertified cables from one of the other posts and enjoy some HDMI roulette. Your money, your choice. Don’t take my word for it, check out some of the reviews yourself 😏.
There ya go, got it off my chest. Phew.
You are correct in that not all HDMI 2.1 cables are the same. Guessing you've been watching LTT's cable testing series.
However, "KabelDirekt" isn't listed as a certified HDMI manufacturer at: https://www.hdmi.org/adopter/adoptersaffiliates?type=ccp
So not sure what makes these "HDMI CERTIFIED"……
