Change phantomjs screen reslotion

I have do some stuff like:

   page.onInitialized = function(){
         window.screen = {width:320, height:640}
    })

It works just in one DOM , if the document has another DOM(like a document has a iframe). that one's screen is 1024 * 768. I cant change it in iframe before iframe's document loaded.

Updated:

Phantomjs default screen resolution is 1024 * 768 when it run in background,but I want to change it to 320 * 640.

And, viewportSize effectively simulates the size of the window(NOT SCREEN RESOLUTION).

You can change it only within onInitialized callback:

function on_init (page){
var width='320',height='640';

//page.viewportSize = {width:width,height:height}
page.evaluate(function (width,height){
screen = {width:width,height:height,availWidth:width,availHeight:height};// window.screen object
//innerWidth=width;  innerHeight=height;   outerWidth=width;  outerHeight=height;
},width,height);};

var page = require('webpage').create(); page.onInitialized=function(){on_init(page)}

Can you just set the viewport default size before opening the page?

page.viewportSize = { width: 320, height: 640 };
