Re: Any suggestions or recommendations?

Shake would be ideal for this kind of shot.

You could set up a four-point tracker for each screen,
comp the four display images together,
then use the *inverted* color key as a kind of four-paned "window"
for the display images to pass through. Or you could do each
display separetely and comp the tracked and "windowed" versions
at the end.

In addition, if you add a little blur to the four-screen comp
before applying the matte, maybe the green-screen spill
on the actors might end up looking like light-wrap.
Nice when you can turn a problem into a feature.
