But that cable also says Ultra HD High Speed Premium HDMI Cable and says 48Gbps.2M of one I linked is £14.44. Note on Belkin one, need to select the 8k cable option which is one that does 120hz @ 4k. 2m of the belkin 8k / 4k@ 120hz one is £60. I suspect your looking at the the normal belkin 4k @ 60hz one is £24.
Here the same cable is on the manufacturers website. Not sure if posting manufacturers sites is allowed, if not let me know or a mod please remove, thanks.
Says HDMI 2.1 certified.
