How about taking the largest one from pygame.display.list_modes()?

Both approaches will fail when you have a dual-head system -- you'll see
a large combined display size (e.g. 2308x1024 for a 1024x768+1280x1024
dual-head mode that crashes pygame when you try to switch to it).  With
gtk.gdk you can at least find the number of screens and their
resolutions.
