When using a classroom computer or any computer connected to more than one display, it’s possible to put Windows 10 into extended desktop. This can be beneficial for programs like PowerPoint allowing one to use “Presenter Mode.” The computers in smart classrooms default to clone displays or duplicate the desktop, meaning the image appearing on the monitor is the same as what displays on the classroom screen.
