1. A computer system for determining relative positioning in a multiple display grid, the computer system comprising: one or more computer processors, one or more computer readable storage media, and programs stored on the one or more computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising: program instructions to receive positioning information from a renderer after the renderer receives the positioning information from, at least, a first sensor and a second sensor operably affixed to at least a first display, at least, a third sensor and a fourth sensor operably affixed to a second display, and, at least, a fifth sensor and a sixth sensor operably affixed to a third display, wherein the sensors include near field communication (NFC) devices, radio-frequency identification (RFID) tags, Bluetooth devices, accelerometers, and gyroscopes; program instructions to analyze the positioning information to determine a relative positioning and orientation between, at least, the first display, the second display, and the third display by creating a sensor pairing associations between the first sensor and the third sensor and between the second sensor and the fifth sensor, wherein a graph is constructed, based on the sensor pairing associations, that represents the relative positioning and orientation of, at least, the first display, the second display, and the third display; and program instructions to generate an extended display on, at least, the first display, the second display, and the third display, based on the analyzed positioning information, wherein images on the extended display are arranged dynamically and seamlessly without user intervention.
