ABSTRACT:
To provide an expanded computer desktop working area, a forking driver is removably inserted logically between a graphical device interface program and a plurality of display device driver programs driving a plurality of computer monitor display screens. When inserted, the forking driver configures parameters for the screens to recognize capabilities common to the screens while also preserving significant capabilities of one of the screens representing a primary screen. The forking driver intercepts a function call directed to the device driver program corresponding to the primary screen and processes the function call to cause one or more of the device driver programs to change one or more screens in a manner consistent with the expanded working area.
