Using the classroom computer, instructors can display the content on the computer or their laptop on the projector. This article covers multiple ways to accomplish this task.

Preferred Method, Windows 10, 8, and 7

  1. Press the Windows key + P on your keyboard. Select one of the following options according to your need:
    1. PC screen only (Screen 1): The laptop will display an image exclusively on the laptop screen. Select this choice when not connected to a projector or secondary display.
    2. Duplicate: The same image will be displayed on both the projector and the laptop screen.
    3. Extend: The projector will act as a secondary screen. This option is useful for giving presentations where presenter notes are used in either Power Point or Keynote. The projector will only show the background image of the laptop until content is placed there or a presentation is started.
    4. Second screen only (Projector Only or Screen 2 Only): the image will not appear on the laptop screen. This option is not as useful in the classrooms.

Information about the built-in classroom computer

You cannot follow the same process using the classroom's built-in computer. 

Classroom equipment has been set up in a manner that enables the classroom to serve multiple purposes. Classrooms are designed to maximize options and meet the broadest needs of the faculty while not becoming so overly complex that service outages result for faculty. 

The behavior of the PC is the most pressing concern when it comes to explaining why enabling this would not be appropriate in our classrooms.

  • If a classroom is configured to meet this specification, a second display can be connected directly to the classroom PC. However, from the PC's perspective, monitor roles could get confused.
  • As displays are turned on and off, the display for different content sources and audio may be routed through to the display monitor instead of the main audio controller. 

The likelihood of these issues occurring is currently too high for this setup to be deployed at the university. Using a laptop is the most practical workaround because a user can extend a laptop screen without encroaching on the classroom equipment's ability to serve the needs of other faculty.
