Abstract
A virtual space for displaying the pointer in a visually correct manner on a multi-monitor computer system is presented. The virtual space is kept separate from the internal display surface of the multi-monitor computer system upon which information is written to be displayed on the monitors. The virtual space is established such that the virtual display areas of the virtual space reflect the visual arrangement of the monitors. The virtual space captures all pointer movements, such as by a mouse or other input device, and moves the pointer within the virtual space. On a pointer update frame, the pointer is mapped from the virtual space to the internal display space such that the pointer may be displayed on the monitors.
