Why is the screen of my notebook computer not displaying my presentation on Acer PE-S42?

If you're using a Microsoft® Windows® based notebook, it might deactivate its own screen when a second display device is in use. Refer to your computer's manual for reactivation instructions. If you're using an Apple® Mac® OS based notebook, open Display in System Preferences and select Video Mirroring "On".
