Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice gs = ge.getDefaultScreenDevice();

    DisplayMode[] dmodes = gs.getDisplayModes();
    for (int i = 0; i < dmodes.length; i++) {
        DisplayMode dm = dmodes[i];
        int refreshRate = dm.getRefreshRate();
        System.out.println(refreshRate);
    }// w  w  w.j  a va2s  .c  o m
