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. Additionally, MaxiVista allows to control up to four PCs with a single mouse and keyboard of the Primary PC. Just drag the mouse cursor to the PC you wish to control. MaxiVista can also mirror the display contents of your primary PC to any other PC via a network connection without signal loss. MaxiVista is based only on software. No need to buy graphics cards, monitors or keyboard mouse switches
