Hi. I am working with a PanelView Plus 6 600 and noticed that the resolution size is the same as the PanelView Plus 6 400. I'm a little surprised because I would assume that the larger screen size of the 600 would allow me to have a a more room for displaying more stuff than the 400. Am I missing something? If it is the same resolution, what is the advantage of a 600 vs a 400?
