Am I limited to the space available on my monitor?  I am trying to get an image of a zoomed version but covering more of the network than I can see on my screen while zoomed in.  I also want more of a portrait shaped image than a landscape shape, but my monitor is more landscape.   Is this possible?
 
Is there a way to make this sizer thing less of a wide rectangle to get more height and less width?

Also, how do I get more labels to show?  The labels don't show for some of the the highest degree actors.
