    • 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.
    • 公开了一种图形卡,多屏显示系统和同步显示方法。 所公开的方法包括以下步骤。 首先,响应于从母板传送的第一时钟信号并行地提供第一时钟信号。 根据并行提供的第一时钟信号之一产生第二时钟信号,其中第一时钟信号的振荡频率大于第二时钟信号的振荡频率。 然后,基于第二时钟信号生成一组显示时钟。 该组显示时钟控制一组屏幕的显示,用于同步多屏显示。
