If you are using a Microsoft® Windows® based notebook: Some notebook PCs may deactivate their own screens when a second display device is in use. Each has a different way to be reactivated. If you are using an Apple® Mac® OS based notebook: In System Preferences, open Display and select Video Mirroring "On".
