I don't believe it matters what HDMI cable you use, as long as it supports 4K. The refresh rate doesn't have to do with the HDMI cable, because the refresh rate relies on the actual television's capability. Same as the HDR, as long as the television has that feature already available basically any HDMI 4K cable should allow the best picture. I personally have a 4K HDMI cable from 'Monster' & I believe it's the platinum cable? Anyways, this cable will do it's job at getting you 4K picture & regarding the 120hz, that'll rely on the television itself.
