Questions about multiple monitors.

Hello, newbie here! I am looking to have several monitors set up in different rooms of our business. Don't want separate computers, but monitors only pulling from main office computer. Either each monitor showing all information about each section of the business (from Excel spreadsheet), or ideally each monitor being able to display only the information pertinent to that division. I am not sure of the terminology of all this to do a Google search, maybe someone can start me in the right direction. Would I need a docking station? Well upload picture to show what I'm interested in... When I can figure out how!
Thanks for any suggestions!

I would recommend a Raspberry Pi at each location. It can run headless off an ethernet or WiFi network connection. An Android TV box might also work.

Thanks for the reply! I've never heard of Raspberry Pi before - that's a good place to start researching!
Thanks agian.
