thats not possible to do. the only thing you could do is use javascript to detect the users screen resolution and then manually get them to pick to pick the new page. that means you will have to create multiple resolutions of youre website though.
Code:
<SCRIPT language="JavaScript">
<!--
if ((screen.width>=1024) && (screen.height>=768))
{
window.location="highres.html";
}
else
{
window.location="lowres.html";
}
//-->
</SCRIPT>
will be what you want to use. check out: javascript: Screen Resolution Detection for the code source.
