```
public class DISPLAY_DEVICE
extends Struct
```
Receives information about the display device specified by the iDevNum parameter of the User32.EnumDisplayDevices(java.nio.ByteBuffer, int, org.lwjgl.system.windows.DISPLAY_DEVICE, int) function.
The four string members are set based on the parameters passed to EnumDisplayDevices. If the lpDevice param is NULL, then DISPLAY_DEVICE is filled in with information about the display adapter(s). If it is a valid device name, then it is filled in with information about the monitor(s) for that device.

Member documentation
- cb – size, in bytes, of the DISPLAY_DEVICE structure. This must be initialized prior to calling User32.EnumDisplayDevices(java.nio.ByteBuffer, int, org.lwjgl.system.windows.DISPLAY_DEVICE, int).
- DeviceName – an array of characters identifying the device name. This is either the adapter device or the monitor device.
- DeviceString – an array of characters containing the device context string. This is either a description of the display adapter or of the display monitor.
- StateFlags – device state flags
- DeviceID – not used
- DeviceKey – reserved
