John,
There are two parts to what you want to do. First you must set the
size of the actual DisplayPanelJ2D component to at least 360 x 180.
_From your message, it sounds like you are not having any trouble
with this part. You're right that you can use
DisplayPanelJ2D.setPreferredSize() to accomplish this:
DisplayImplJ2D display = new DisplayImplJ2D("display");
DisplayPanelJ2D panel = (DisplayPanelJ2D) display.getComponent();
panel.setPreferredSize(new Dimension(400, 200));
Secondly, follow TomW's instructions for setting the aspect ratio
of the display. For a Java2D example, see visad/examples/Test58,
which sets the aspect ratio in Java2D to a rectangular region like
you describe.
