Abstract:
1. A method for controlling multiple displays, adapted to control a plurality of graphics processing units to simultaneously draw a display frame, wherein each of the graphics processing units controls at least one display, the method for controlling multiple displays comprising: providing a new graphical interface the same as an existing graphical program library of an operating system, wherein only one display frame and only one graphics processing unit are recognizable by the existing graphical program library of the operating system, and wherein multiple display frames and multiple graphics processing units are simultaneously recognizable by the new graphical interface; intercepting a drawing command from an application program to the existing graphical program library through the new graphical interface; determining a display set of the graphics processing units according to a display region of the application program, wherein a display region of the display controlled by each of the graphics processing units in the display set is intersected with the display region of the application program; performing coordinate transform on the drawing command to generate a coordinate-transformed drawing command according to the display region of the display controlled by a corresponding graphics processing unit in the display set; and delivering the coordinate-transformed drawing command to the corresponding graphics processing unit in the display set.
