A precision multi-view (MV) display system can accurately and simultaneously display different content to different viewers over a wide field of view. The MV display system may include features that enable individual MV display devices to be easily and efficiently tiled to form a larger MV display. A graphical interface enables a user to graphically specify viewing zones and associate content that will be visible in those zones in a simple manner. A calibration procedure enables the specification of content at precise viewing locations.
