ASUS ROG GL502VS-DB71 upgrading display to a 120hz one?

So I want to upgrade my display. But panel look doesn't seem to show anything more than the frequency being 60hz with a question mark. Here is the info I've found and potentially best displays to upgrade to. Please give some advice for which to choose or how to find out how to upgrade to a 120hz display. I did also see the revision of the 15" laptop from Asus which has a 120hz panel which I think would probably be ideal but I can't find any info about it.

This is what I found. The issue si I can't find out what panels are g sync, which ones are 120hz on panellook.
