How to tell the difference between X34, X34A and X34P?

[conquista90]

So i have this online seller claiming to sell an X34P predator monitor.. but in the description the refresh rate is only 100 if OC. Another seller is selling an X34A with the same description but at a higher price because its newer. so i'm a bit confused.

This is the link to the X34P online site.

This is the link to the X34A online site.

Coming back to the question... How do i physically differentiate the three and isn't it supposed to be X34>X34A>X34P (old to new)
