120hz on the ps5?

I want to buy a full-hd 144hz monitor for my PS5. At 1080p it supports 120hz. But I often read that some monitors do not support the 120hz on the ps5 and am afraid to buy the wrong one. Where can I see that the monitor with hdmi 2.0 creates the 120hz on the ps5 and do you know monitors, where are you sure that they can do it?

You need a monitor that supports 2.1 and a cable with 2.1. Strangely, that's not included with the ps5

Here is a selection:

Definitely for climate protection reasons.

I only need 2.1 if I want to play on 4K with 120hz, right?

It's probably because of that

4k with 120hz is not possible anyway.

With 2.0 you can play on 4k as far as I know but you can't reach 120hz.

At least got it that way
