and Horizontally (along side). · Associate the mouse cursor with each computer based on its
respective display position. · Consider all displays as one absolute screen area to allow VDT. · Virtual Display Technology (VDT) – Switch control between PCs
by moving the mouse cursor across display boarders (all over the absolute screen area).
