Assembly: Microsoft.Xna.Framework.Game (in

public class GraphicsDeviceManager : IGraphicsDeviceService, IDisposable, IGraphicsDeviceManager

Custom behavior of the GraphicsDeviceManager can be achieved by deriving a class from GraphicsDeviceManager. For example, to allow only widescreen devices in full-screen mode the RankDevices method could be overridden to drop non-widescreen devices.

By adding an event handler for the PreparingDeviceSettings event to the GraphicsDeviceManager, you can control the PresentationParameters properties associated with the graphics device. In the example below, the event handler is named graphics_Settings_NoDepthBuffer.

graphics = new GraphicsDeviceManager(this);
graphics.PreparingDeviceSettings +=
    new EventHandler<PreparingDeviceSettingsEventArgs>(
