Max Window size in different monitors

You can get all your screen sizes with code like @Carl.Gould suggests in the other thread you posted in:

from java.awt import GraphicsEnvironment

env = GraphicsEnvironment.getLocalGraphicsEnvironment()
for i, screen in enumerate(env.getScreenDevices()):
	size = screen.getDefaultConfiguration().bounds
	print "Screen %i is %dx%d" % (i, size.width, size.height)

Output when tested in script console with a couple monitors:

>>> 
Screen 0 is 1366x768
Screen 1 is 1920x1080
>>>
