Abstract
Abstract A system and method for a computer system to recognize and initialize an arrangement of a plurality of physical monitors as a single logical screen (SLS). The invention translates a user's window operation request directed to the SLS into an SLS function. The SLS function is then translated into a plurality of device dependent functions, each of which performs the user's requested window operation on one physical monitor. The translation of the SLS function comprises an unwrapping of the SLS function by removing the SLS function and installing the plurality of device dependent functions, and the wrapping of the plurality of device dependent functions by removing the plurality of device dependent functions and installing the SLS function. The invention implements each of the unwrapping and wrapping operations in two assignment instructions. The invention further comprises the capability of generating a single simultaneous display wherein the image on one physical monitor is displayed on each physical monitor of the SLS configuration.
