A:AnswerSince it's not certified I think it is 2.0. Because HDMI 2.1 can do 48 megabytes per second and in the listing says it maximum can do 18. Meaning that it won't be able to do 4K at 120 frames per second. If you want an inexpensive certified 2.1 cable I would recommend UGreen not sure if Best Buy sells it but I have seen it on Amazon. Also if you are in store Best Buy also sells Best Buy Essentials 2.1 certified HDMI cable 6 ft for like $15 last time I checked.
