Imports
javax.annotation.*, java.nio.*, org.lwjgl.*, org.lwjgl.system.*
Receives information about the display device specified by the iDevNum parameter of the User32#EnumDisplayDevices 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.
