Java: Getting resolutions of one/all available monitors (instead of the whole desktop)?

Question

I have two different-sized monitors, connected together using (I believe) TwinView.

I tried

System.out.println(Toolkit.getDefaultToolkit().getScreenS         


        

Answer 1

you'll want to use the GraphicsEnvironment.

In particular, getScreenDevices() returns an array of GraphicsDevice objects from which you can read the width/height of the display mode.

Example:

GraphicsEnvironment g = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] devices = g.getScreenDevices();

for (int i = 0; i < devices.length; i++) {
    System.out.println("Width:" + devices[i].getDisplayMode().getWidth());
    System.out.println("Height:" + devices[i].getDisplayMode().getHeight());
}
