Ordered LG OLED C1 - HDMI 2.1 "cable"?

[ShivP]

Hi all
We have ordered a 77C1 LG OLED
We have 2 generic HDMI cables currently which seem happy running at 4k60 to the current TV, however unsure whether they'll support 4K120. Currently the boxes etc go through the Denon amp AVRX2300W, I understand this doesn't support 4K120 so one of the cables would need replacing

My question: is there such a thing as HDMI "2.1" cables, or should all cables support it?

Thanks

You want an 'Ultra High Speed' certified cable to ensure full functionality of HDMI 2.1 features and throughput.
