 5             if (presentation.IsFullScreen)

 8                 graphics.PreferredBackBufferHeight = 600;
 9                 Window.AllowUserResizing = false;
10             }
11             else
12             {
13                 GraphicsAdapter adapter = graphics.GraphicsDevice.CreationParameters.Adapter;
14                 graphics.PreferredBackBufferWidth = adapter.CurrentDisplayMode.Width;
15                 graphics.PreferredBackBufferHeight = adapter.CurrentDisplayMode.Height;
