 In exactly the same way as the first one, there is no difference between
them.

 You do need to use wxDisplay::GetGeometry() and I am pretty sure it's not
a good idea to do what you want (consider the case of a primary screen in
the centre and 2 other displays at its sides -- how exactly are you going
to draw your image?) but this shouldn't prevent you from doing it...
