Definitions
- the present invention relates to a computer. More specifically, the present invention relates to a display of a computer.
- a computer user has to concurrently watch a plurality of screens while doing jobs through the computer. For example, since stock dealers must keep up with worldwide fund flows, they must receive different screens through a plurality of monitors. Also, in the case of simulation games, it is necessary that the gamers concurrently enjoy situations created in different positions of a map of the simulation game.
- graphic cards to a computer so that the computer may display identical images to a plurality of image output devices or display different images to the respective image output devices.
- a computer with a plurality of image output devices comprises: a signal input unit for generating N (N represents a natural number equal to or greater than two) graphic data processing signals according to a user's intention; a data storage unit for storing drivers for processing various application programs and graphic data used in the computer, and other kinds of data; a central controller for enabling a driver to divide graphic data generated when processing the data according to the N graphic data processing signals input from the signal input unit, and to output N driving signals; N graphic data processors, each for receiving one of the N driving signals output by the central controller to be operated, processing - graphic data corresponding to the received driving signals to output image signals; and N image output units, each for receiving one of N image signals output by the N graphic data processors, converting it into a visual signal, and outputting the same to a user.
- N represents a natural number equal to or greater than two
- the signal input unit is at least one of a keyboard, a mouse, a remote controller or a touch screen.
- the first graphic data processor is a graphic card.

- the N th image output unit 160 functioning as a CRT or an LCD
- the first to N th slots 127 to 147 may be connected to
- PCI peripheral component interconnect
- the central controller 120 enables a driver stored in the data storage unit 1 10 to reside in a random access memory (RAM) (not illustrated.)
- RAM random access memory
- the signal input unit 100 such as a keyboard or a mouse
- the signal input, unit 100 outputs the first to N th graphic data processing signals to the central controller 120.
- central controller 120 controls the driver that resides in the RAM, divides the
- N th graphic data processors 130 to 150 process the corresponding graphic data divided by the central controller 120, respectively output them to the first
- 140 to 160 convert and output them so that the user may visually recognize
