I am looking to design a small computer lab for my workplace. I am hoping to have the work be shared onto one monitor that will be displayed in the front of the room, large enough for people working to see. In practice, it should be multiple inputs, on one output, if that makes sense. For example, if we are all working on the same project, and someone edits something, I want that project that is being displayed to update in real time. Here is an idea of what I am trying to accomplish, some help would be appreciated! Here is an image of what I am trying to accomplish, it is a bit of a crude drawing but hopefully it makes sense!
