# Class DisplayMode

java.lang.Object
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.

  1.4
