bump map scale change with the resolution of rendering

[seblezinzin]

Hello,
I've a problem with my bump map.
I'm workinng on a boat rendering with sea.
I created my sea with the water material and a sea map for the bump.

But when I make my rendering with a little resolution as my screen (1920*1080) the result is the same that in keyshot,
But when I make my rendering in HD (8000*5000) the bump map is more little , and it's not good for me beacause reflects change.....
