Multiple Monitors (at different locations) connected to one CPU

I would like to connect multiple monitors to one CPU and be able to place these monitors at different locations on the shop floor. I would like these monitors to display the same image from the host computer. I would like to change/update information on a host/primary computer and have that information display at multiple locations through the monitors. Can this be done? What additional hardware and/or software do I need to purchase other than the monitors and the host computer?
