media query

@media only screen and (-webkit-min-device-pixel-ratio: 2),
       only screen and (min-resolution: 2dppx){

       // css for high resolution display here 
}

Attension of media query solution

You should use resolution property to specify high resolution display. Because device-pixel-ratio is non-standard property. But iOS safari dose not support resolution property.

Actually, You need to use both property.
