If you're using a browser, why not just dump some Javascript in there, like this:
<script language="JavaScript">
var width = window.screen.availWidth
var height = window.screen.availHeight
alert(width + "*" + height)
</script>
Consult the Netscape and Microsoft object model documentation on the following properties:
screen.width
screen.height
screen.availWidth
screen.availHeight
document.body.clientWidth
document.body.clientHeight
