MaxiVista turns any spare Laptop or Tablet PC into a second monitor for your primary PC. Program windows can be extended across both PC`s screens, while the programs are still all controlled from the primary PC. Simply connect up to four PCs via Ethernet, a wireless LAN, FireWire, or a USB network and enjoy giant desktop real estate of up to 7,680x1,200 pixels. The extra desktop space helps to avoid switching back and forth between overlapping windows.
