media Query for macbook pro 15"

I'm trying to apply media query for laptop 15" and smaller with no success.

Here is my media query:

@media screen and (min-device-width: 1200px) and (max-device-width: 1600px) and (-webkit-min-device-pixel-ratio: 1) { }

And:

@media screen and (min-device-width: 1200px) and (max-device-width: 1600px) and (-webkit-min-device-pixel-ratio: 2)  and (min-resolution: 192dpi) { }

I works for 13inch macbook pro but no for the 15".

Any help would be much appreciated.

Thanks
