What is the function key for projector in presentations?
The function key for projector in presentations varies depending on the laptop model and brand. However, the most commonly used function keys for projector are Fn + F4, Fn + F5, Fn + F7, or Fn + F8. It is essential to check the laptop’s user manual or manufacturer’s website to determine the specific function key combination for the projector.
Some laptops may also have a dedicated button for projector, usually labeled as “CRT/LCD” or “Display Switch.” Pressing this button will toggle the display output between the laptop screen and the projector. It is recommended to familiarize yourself with the laptop’s keyboard layout and function keys before a presentation to avoid any technical issues.
How do I switch between the laptop screen and projector during a presentation?
To switch between the laptop screen and projector during a presentation, you can use the function key combination specific to your laptop model. For example, if the function key combination is Fn + F5, press and hold the Fn key and then press the F5 key. This will toggle the display output between the laptop screen and the projector.
Alternatively, you can also use the Windows key + P shortcut to switch between the display modes. This shortcut will open the “Projector” window, which allows you to choose from four display modes: “Computer only,” “Duplicate,” “Extend,” and “Projector only.” Selecting the desired display mode will switch the output between the laptop screen and the projector.

Windows offers four display modes that can be used during a presentation: “Computer only,” “Duplicate,” “Extend,” and “Projector only.” The “Computer only” mode displays the output only on the laptop screen, while the “Projector only” mode displays the output only on the projector. The “Duplicate” mode displays the same output on both the laptop screen and the projector, and the “Extend” mode allows you to extend the desktop across both displays.
Choosing the right display mode depends on the presentation requirements. For example, if you want to show the same output on both the laptop screen and the projector, select the “Duplicate” mode. If you want to use the projector as an extended desktop, select the “Extend” mode. It is recommended to experiment with different display modes before a presentation to determine which one works best for your needs.
