Abstract
A graphics card, a multi-screen display system and a synchronous display method are disclosed. The disclosed method includes the following steps. Firstly, first clock signals are provided in parallel in response to a first clock signal transferred from a motherboard. A second clock signal is generated according to one of the first clock signals that are provided in parallel, wherein the oscillation frequency of the first clock signals is larger than the oscillating frequency of the second clock signal. Then, a set of display clocks are generated based on the second clock signal. The set of display clocks control the display of a set of screens, for synchronous multi-screen display.
