4K TV - how much Hertz?

I would like to buy a new TV for the Ps5 with 4K and 65 ". My two current favorites are the Samsung Q60R and Samsung RU8009. Unfortunately I can't find a clear indication how much Hertz these TVs offer. I would like one with 100Hz but there's something everywhere Other: 120 on amazon, 100 on geizhals, 50 in a ct magazine. How do I know what's right?

The Q60R has a refresh rate of 100Hz and the RU8009 has a refresh rate of 100-120Hz.

https://www.produkttest24.com/im-test-samsung-ue65ru8009-premium-4k-uhd-tv/ write that the RU8009 has a refresh rate of 100Hz.

But how can you be sure of that? As I said, I did research and read something else everywhere.

I compared several pages and data sheets and each model in 65 "version was 100Hz. Apart from the RU8009 there was 100-120Hz on one side.

Thanks a lot

My pleasure.
