All staff and student laptops are configured with an idle lock timer – after 15 minutes of inactivity, the screen will lock. While some software, such as Windows Media Player when showing a full-screen video, can automatically prevent the screen from locking, other software cannot do this.
To prevent your screen from locking during a presentation, run the “Presentation Settings” shortcut located on your desktop.
This will open the Presentation Settings application. Check the checkbox next to “I am currently giving a presentation” to enable these settings. Conversely, uncheck it once you have finished your presentation. You can optionally show a different desktop wallpaper during presentation mode. Be sure to click “OK” to enable presentation mode.
