You might be able to test this by querying the HttpRequest.Browser method. Alternatively, there's a Screen object available to javascript of NS/IE 4+ I think it is.

You'll find most sites generall target a specific size (probably 800*600 or 1024*768) & the site will display at that size no matter what your resolutions set upto, or they will use % in their HTML to account for any browser size. I.e. <INPUT Type="Text" width="100%" Style="width:100%"> for example.
