Question

New HDMI HDR cable?

I use AT&T Uverse cable company.
(Not Direct TV).
I already have UHD HDMI cable connected to my TV. Not sure if that cable is HDR compatible. I bought a new Samsung UHD TV with HDR. Not sure if it is also 4K. The salesman recommended buying a new HDMI cable that Is HDR compatible, so I bought the cable.
The guy from the Geek Squad came and installed the new TV. I showed him the package for the new cable. Not sure if he noticed it is HDR compatible.
He said I don't need it and I should return it, that the old one is good enough. He said the UHD is inside the TV and I won't need a new HDMI cable unless I buy a 4K DVD player. I forgot to discuss the HDR aspect of the new cable with him. Not sure if that matters.
Should I return the new HDMI cable, or have it installed to replace the old HDMI cable?

No such thing as a HDR HDMI cable.

Name of Cable

I should mention the cable name is "Rocketfish HDMI Cable 4K Ultra HD and HDR Compatible".
Do I need that for HDR?

No.

HDMI cables are pretty much all the same. At first some makers would not put in the wires for ARC or such but for 7 bucks the AmazonBasics HDMI cable does it all.

Cable for HDR

Thanks for the info regarding that I don't need this UHD HDMI cable I just bought that is HDR compatable, because all the UHD HDMI cables are HDR compatible, including the one I am currently using.
I did a search. There was a Forbes article that HDMI cables wear down over time and lose their effectiveness.
So I may keep this new HDMI cable I bought and use it to replace the HDMI cable I now have in a few years.
Thanks

Sure maybe in decades.

You have to remember that "high end" cable makers have to sell their cables. I want to tell folk in the store that the 100 buck cables are well, good looking but work no better than the AmazonBasics that we pay no premium for.

Please provide a link to that article

I do not believe that is what was written.
