The black screen is the screen saver. If you're using a pc, then from the Control Panel go to Appearance and Personalization, then click on Change screen saver, which is located under the first heading, Personalization. In the middle it says Wait ___ minutes...you can change it here. You can also change what you want to be displayed for your screen saver and whether or not you want to return to the login screen after leaving the screen saver.
