This is just speculation, but this is what I figure:
1. Primary monitor tells VGA adapter that it can support 7680x1024 2. VGA adapter sends 7680x1024 signal to primary monitor 3. Primary monitor only displays leftmost 1280x1024 pixels 4. Primary monitor sends remaining display data via USB back to PC 5. PC segmentizes raw data from USB port 1 to various next USB display devices. Since USB devices can be attached via hubs, just like ethernet interfaces, you can 'daisy chain' them via 5 hubs or hang them off 1 hub.
At least that's how I try to reconcile it in my mind. In actuality, I have no idea how how they do this.
