The fundamental problem is that the theme selection must be done at PHP runtime on the web server, while any JavaScript used to determine resolution (or view port size) will run well after this stage at the client.  With a strait forward approach of PHP running on the server to deliver a webpage, there is no way for the PHP to know the screen resolution at runtime. 

But, it is possible if you take a two stage approach, I don't know of any theme that actually does this though (but that's not to say that there aren't any).

Stage 1 is the initial page request.  The PHP runs and serves JS to the client.  When that JS runs, it can determine the screen resolution and use the values for the request of the second stage.

Stage 2 is the JS requesting that same page again, but with the resolution values as part of the request.

A snippet could roughly look like this:

<?php
if ($_GET['screenx'] && $_GET['screeny']) {

 // $_GET['screenx'] and $_GET['screeny'] are our resolution values
 // make any decisions you want based on them, theme selection, etc..

}
else {
  // this assumes HTTP, adapt as needed.  Use request_uri() to work on non apache servers too
  $url = 'http://' . $_SERVER['SERVER_NAME'] . request_uri();
  print <<<ENDJS
  <script>
    location.href = $page + '&screenx=' + screen.width + '&screeny=' + screen.height;
  </script>
ENDJS;
  exit;
}
?>

Keep in mind though that if you are turning each request into two requests you could run into performance issues.  Better to store the resolution values in $user['session'].

The resolution depends on your browser's size. You can be with a
resolution of  1280x1024 but your browser with a size of 800x600.

    I think you can do this with java script

    <script type="text/javascript">
    function alertId()
    {
    alert(screen.width);
    alert(screen.height);
    }
    </script>

    Now you know the resolution of user, just call the required
    theme. Module is not required for this .
