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

public DisplayMode(int width,
                   int height,
                   int bitDepth,
                   int refreshRate)
```
    Create a new display mode object with the supplied parameters.
    
    Parameters:
    
    width - the width of the display, in pixels
    
    height - the height of the display, in pixels
    
    bitDepth - the bit depth of the display, in bits per pixel. This can be BIT_DEPTH_MULTI if multiple bit depths are available.
    
    refreshRate - the refresh rate of the display, in hertz. This can be REFRESH_RATE_UNKNOWN if the information is not available.
