I recently bought an LG OLED C1 and needed a good HDMI 2.1 cable for fast transfer and this one worked great because all I needed to do was connect it to the eARC located in hdmi2 on the tv otherwise the connection to the pc will keep turning off if I use any other port so this is the only port that supports it and only this cable and the Belkin work so all in all it was worth the purchase finally I had no audio or visual black screens even when I use Gsync 1440p at 120hz
