Get Monitor Screen Resolution with Javascript
Find out and display a user's screen resolution with javascript.
In javascript, the screen.width and screen.height properties contain the size a visitor's monitor is set to. Bear in mind that the size the monitor is set to is not the same as the size of the browser window a visitor is using - windows can of course be set to different sizes. To find out this information you need to check the height and width of the viewport (different methods for different browsers, unfortunately).
Your current screen resolution (if you have javascript enabled) is
To display a visitor's screen resolution, simple include the following code in your page:
<script type="text/javascript">
document.write(screen.width+'x'+screen.height);
</script>Screen resolution redirect
Once you know what a visitor's screen resolution is, you can redirect them to a particular page. Admittedly, you'd be better off with a page that worked at any screen resolution, but anyhow ;)
The script below will redirect users based on whether or not they have a monitor resolution of 800x600 or below:
<script type="text/javascript">
if ((screen.width<=800) && (screen.height<=600)) {
window.location.replace('http://example.com/800-600-or-less');
}
else {
window.location.replace('http://example.com/greater-than-800-600');
}
</script>

Screen resolution is given in pixels per meter, or similar. screen.width does not give screen resolutions.

JayZ - screen or display resolution is the agreed terminology to refer to the pixel dimensions of a screen. You could argue that this is not entirely accurate, but generally people refer to PPI/DPI using different terminology - that's just the way the language has evolved. Don't blame me ;)

this might be helpfull, this code gets the resolution with java then makes php variables with it:
var reswidth= (screen.width)
var resheight= (screen.height)
just make a file called: getres.php, and you can include it in any php file with:
require("getres.php");
$reswidth; is the width only,
$resheight; is the height only,
$res; is width x height.
hope it helped.

What would the argument be for else if you just wanted the browser to stay on the current page?
