How to get screen resolution under Win32?
Check out Aldo Calpini's chres.pl. It gets\sets the screen settings.
You probably already know this, but this method will not work in a CGI environment - i.e. you can't get the resolution of a remote user's screen via a webpage without a client-side script such as javascript. But I'm the wrong person to ask about that :)
Update: Aldo's site appears to have changed since I was last there - and I can't find anything related to perl. The above URL is the same one listed for him on CPAN. ?
