(English: graphic card graphics card or video adaptor, video, video display board, display board, adapter, video adapter, and then it will be called) is a device that receives information about the display from the memory and processor, and then send the information in a video signal to the video device (usually the monitor)Old video card converts digital information into the signal only. But the stream of 3-d acceleration card In the second half of the 1990s by 3dfx and nVidia make 3-d technology development. Modern video cards now include the ability to display 3D images into a standard and have called a new name that the GPU (Graphic Processing Unit) you can reduce the Visual effects of central processing unit (CPU) of many.At present, many video cards do not exist in the form of cards, but they are part of the motherboard, which serves the same. These display circuitry, there are 3-d capabilities are somewhat limited, but it is suitable for Office, Web-based email reader, play, etc. For those who want such a marvelous 3-d capabilities used to play computer games. The hardware is in the form of additional plug adapters to get the animation as a realistic 3D. On the other hand, Some applications, such as medical I want the ability to display two dimensions height instead of the three-dimensional.The original 3D video cards are cards with separate two-dimensional cards and connecting cable is connected, such as 3dfx Voodoo cards of which there is no current. At present, there are three dimensional video output capabilities in two dimensions.
