I have recently been using scripts to view multiple bands of the same images. It is useful to display the various bands in different displays. It is helpful to set a sharing group so that the displays share views when zooming or panning the image. This can also be done from the script:
panel1=buildWindow()[0]
panel2=buildWindow()[0]
panel1.setShareGroup('group 1')
panel2.setShareGroup('group 1')
panel1.setShareViews(1)
Thanks,
