Field of the Invention The present invention relates to a display system, and more particularly to a display system having a plurality of monitors. [Prior Art] In order to increase the number of monitors for a computer system, there are two methods for achieving the display system of this multi-monitor. One of them is to insert an add-on graphics card into the computer system; the other is to achieve this by connecting the wired display device externally to the computer system. Obviously, the main disadvantage of inserting a graphics card into this computer system is that the chassis or housing of the computer system needs to be opened. So there will be security issues. In addition, the volume of this computer system must be large for the expansion of such graphics cards. This can solve the above problem for a wired display device. However, there are still some weaknesses in the current products. The current solutions for such wired display devices can be divided into two methods, but both use a Universal Serial Bus (USB) interface. One of the methods uses two wafer solutions, including a β$β_转一pc! (Peripheral Component Interconnect) (USB-t〇-pci) bridge wafer and display wafer. This method requires an external bridge chip because the display does not support the USB side. The need to bridge wafers also adds to the cost and design complexity of this wired display device. This is similar to the previous development of a special application integrated circuit (ASIC), which integrates the bridging function and display function into a single chip. Both methods use the central processing unit (CPU) of the computer system instead of the graphics processing unit 200825897 (GPU) to process the graphics data. Therefore, both methods greatly increase the computational load of the CPU. In addition, both methods require a specific software application (Ap) to draw this display. In addition, the Video Graphics Array (VGA) device is not defined in the USB standard class, so that developers must develop a special display method for these wired display devices. ). This special application or driver also means a lot of cost, time, and research and development resources. Furthermore, the current bandwidth is limited to 480Mb/s. In this case, no matter how powerful the function of the computer system (10) is, this is for high-definition (10) video playback or three-dimensional space (10) instant application. In fact, it is not enough. Therefore, there is a need to provide a new display system to address these problems. SUMMARY OF THE INVENTION The present invention is directed to reducing the overall cost of such a wired display device. Another object of the present invention is to reduce the design complexity of the wired display device. Another object of the present invention is to use the PCI E_P ess speed interface as a graphics data transfer wheel.

GPU to achieve a multi-monitoring Another object of the present invention is to display the system by a general graphics processor without any specific software. The illuminator & display system does not increase significantly. Another object of the present invention is to achieve the burden of a central processing unit (CPU). 200825897 Therefore, in order to achieve - or - some or all of the above purposes, this display secret includes: a computing system; - Lian Lin, which can transfer material p called ess money; - Qing processing _ and, through the 峨 (four) (four) booty Sigh, face-shaped processing module, and can display image data.
