Thanks for all the responses, last night I found the solution I'm looking for :-)

Here's a way of getting the monitor geometry for Win32 multi displays:

<code>
foreach my $display (Gtk2::Gdk::DisplayManager->get->list_displays) {
	print "display name [", $display->get_name, "] num screens [", $display->get_n_screens, "]";

	my $defaultScreen = $display->get_default_screen;
	print "\tscreen num monitors [", $defaultScreen->get_n_monitors, "]\n";
	for(my $monitorNumber = 0; $monitorNumber < $defaultScreen->get_n_monitors; $monitorNumber++) {
		my $monitorGeometry = $defaultScreen->get_monitor_geometry($monitorNumber);
		print "\t\tmonitorNumber [$monitorNumber] geometry h [", $monitorGeometry->height, "] w [", $monitorGeometry->width, "] x [", $monitorGeometry->x, "] y [", $monitorGeometry->y, "]\n";
	}
}
</code>

I suppose the '->list_displays' loop is unnecessary for Win32, but this way it can be made to work for both Linux and Win32, although a loop is required for the screens under Linux.

Thanks
