If you select "Turn off monitor when blanking the screen" and minimize to systray, log is growing fast with several repeating lines:

[ERROR][MPMain(1)]: GraphicContext: Error setting Blankscreen to True - System.NullReferenceException: Objektreferensen har inte angetts till en instans av ett objekt.
vid MediaPortal.GUI.Library.GUIGraphicsContext.set_BlankScreen(Boolean value)
