I made a responsive website which works fine with different screen resolutions. I use three different media queries - from 0 to 640, from 640 to 960 and above. Anyway if I try to open on my Samsung Galaxy Note2 which uses 720x1280, since it has pixel ratio 2, it reads the website as 360x640 device, but with 640-960 styles.

How can I be sure that the website will be displayed in original resolution?

I included this in the header:

<meta name="viewport" content="width=720, initial-scale=1, maximum-scale=1, user-scalable=no" />

If I add something like this in my stylesheet file

@media (-webkit-min-device-pixel-ratio: 2), (min-resolution: 192dpi) { 
@viewport {
     max-zoom:50%;
     width:720px;
}
}

It works OK in Chrome's Emulation Mode, but not if I test it on the real mobile.

EDIT: Woo-hoo... I found a way to do that with JavaScript.

document.querySelector("meta[name=viewport]").setAttribute('content', 'width=device-width, initial-scale='+(1/window.devicePixelRatio)+', maximum-scale=1.0, user-scalable=0');

It reads device pixel ratio and then sets the initial-scale value.

This....maximum-scale=1, user-scalable=no" is not recommended. It's just poor user experience.Paulie_D
@Paulie_D I know, but the website is made that zooming shouldn't be the good idea and basically cannot be avoided.kosijer
Thanks! Just what I was looking for. Calling that javascript can be done, if the user wants to show the screen as seen in the desktop. Very helpful at times.rsmoorthy

I haven't tested this, but try changing:

<meta name="viewport" content="width=720, initial-scale=1, maximum-scale=1, user-scalable=no" />

to

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" />

Setting the width to 720 would explain why your 640-960 styles are being applied.
