## 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.

  Since:
    1.4

    - #### DisplayMode

          public DisplayMode​(int width,
                             int height,
                             int bitDepth,
                             int refreshRate)

      Create a new display mode object with the supplied parameters.
      Parameters:
