Usage

From source file:Main.java

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

    boolean canChg = gs.isDisplayChangeSupported();
    if (canChg) {
        DisplayMode displayMode = gs.getDisplayMode();
        int screenWidth = 640;
        int screenHeight = 480;
        int bitDepth = 8;
        displayMode = new DisplayMode(screenWidth, screenHeight, bitDepth, displayMode.getRefreshRate());
        try {//from   www . j a  v a 2s .  c o  m
            gs.setDisplayMode(displayMode);
        } catch (Throwable e) {
