-resolution dots-per-inch
By default, G2 displays a window at 75 dots per inch (dpi).
Special Considerations

g2 -x-resolution 75 -y-resolution 100
-resolution option with either the -x-resolution or -y-resolution options. If you specify the -x-resolution option, you should also specify the -y-resolution option, and vice versa.
