Abstract
A computer providing multiple display capability where one display presents the current document and another display may show a true display of a previously opened document. The computer is a singular processed video data signal source which presents a primary monitor with current video data. A user selected video screen sample of the current processed video data signal is diverted to this invention where it is stored in a memory. Subsequently the stored video screen sample of the processed video data signal is read-out of the memory and reconstituted as an absolute copy of the original processed video data signal and concurrently presented on a secondary monitor. User selection may be attained by a keyboard key-sequence entry, a mouse button click or using an external button-switch. Operation is absolutely independent from operating system constraints, being of equivalent usefulness while running any Operating System versions of Windows.RTM., Unix, MS-DOS, Linux, CP/M86 or Apple-OS. The device is preferably configured as a standalone peripheral, having two video ports connected essentially between the computer's 'video output' port and the primary monitor's 'video input' port and a third video port coupled with the secondary monitor's 'video input' port.
