displayport question, first time user

[RavenX]

May be a stupid question to a lot of you however I just picked up an RTX 2080 ti. Its replacing my old GTX 980. I also replaced my old 24 inch monitor with an Asus PG27UQ 4k. Mainly going to play some of my older games that were released a few years back so 4k at 120hz shouldn't be a problem. Now to my question since I'm new to displayport as I've always used dvi, to get the full 120hz, when choosing a cable, do I need to make sure its a diplayport 1.4 cable or will any displayport cable work even if it doesn't say 1.4? Reason I ask, when looking on amazon, there are cables that say they are 1.4 and others that do not.

This one says its 1.4

This one does not

You need DP 1.4 with HBR3.

This cable should work:

Most of the other cables will limit to 60Hz at 4K.
