The invention provides a method for realizing multi-screen playing video, comprising steps: finishing the connection and management of plural video cards and display devices; the computer reading the display resolution gross data and the number of the display device, recording the relative position number of respective display device; CPU calculating a dividing way of an entire video image frame based on the quantity of the display device and the number of the relative position, determining the display device number and the divided zoom ratio corresponding to respective divided original resolution video image data block; CPU dividing each frame video image data of the multi-screen playing video file to plural original resolution video image data blocks based on the dividing mode, transmitting each data block to the corresponding display card by a bus; each display card processing zoom to the original resolution video image data block according to the zoom ratio and displaying on the display device. The invention improves the refreshing rate of the multiple-screen playing, reduces the CPU occupation resource and achieves the real time playing effect.
