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()).
