At home I have a laptop and external monitor, but logmein only permits a single monitor in the active window (web browser) and has a toggle to view alternate monitors. The resolution isn't high enough to view both machines if I have one window "span" both of my remote connected monitors.
Hope this helps.

Thanks a lot,
