java.awt.DisplayMode

public final class DisplayMode
extends Object

The DisplayMode class encapsulates the bit depth, height, width, and refresh rate of a GraphicsDevice. The ability to change graphics device's display mode is platform- and configuration-dependent and may not always be available (see GraphicsDevice.isDisplayChangeSupported()).

For more information on full-screen exclusive mode API, see the Full-Screen Exclusive Mode API Tutorial.
