Come posso modificare il codice sottostante affinchè il fullscreen sia ottimale indipendentemente dalla risoluzione video dell'utente?

<HTML>
<HEAD>
<meta http-equiv=Content-Type content="text/html; charset=ISO-8859-1">
<TITLE>provafull</TITLE>
<html>
<head>
<script>
function screenFull() {
// (c) br1 - 2001
if (document.all) {
// misuro lo schermo
sW=screen.width;
sH=screen.height;
// porto la finestra a 0,0 e misuro bordi
window.moveTo(0,0);
gL=window.screenLeft+2;
gT=window.screenTop+2;
// altre cose da eliminare...
gR=22; // scrollbar a destra
gB=49; // scrollbar sotto e status
// sorpresa!
window.moveTo(-gL,-gT);
window.resizeTo(sW+gL+gR,sH+gT+gB);
}
}
</script>

</HEAD>
<body onload="screenFull()" bgcolor="#000000">
<center>

<A HREF=javascript:window.close('provafull.html','',' fullscreen=0,scrollbars=0');void(0);></A>
