A method and apparatus that partitions a single display's viewable area into at least two virtual viewable areas, and emulates the at least two virtual viewable areas as at least two emulated physical displays with an operating system such that the operating system behaves as if interfacing with at least two actual independent physical displays. The method provides the operating system with generated display identification data (such as 'EDID') for each of the emulated physical displays in response to a query from the operating system. The method and apparatus also receive notification of an interrupt (where the interrupt corresponds to the single physical display), and reports to the operating system with at least two sets of interrupt reporting information, corresponding to the at least two emulated physical displays, as if two interrupts were received. The operating system is thereby 'faked' into acting as if two physical displays are in operation.
