What should you do to make a video play in full screen mode during a presentation?

To ensure that a video plays in full screen mode during a presentation, the Play Full Screen option found in the Playback Tab should be selected. This option specifically configures the video playback settings to display the video in full screen when it is played. It streamlines the process, allowing for a more professional presentation without the need for manual adjustments during the actual presentation.

Other options, while potentially useful in other contexts, do not facilitate full screen playback in the same direct manner. Adjusting the video size manually doesn't guarantee that the video will fill the entire screen properly and may lead to distortion. The Format Video options primarily focus on styling and visual appearance rather than playback mode. Right-clicking on the video to select Full Screen can be a workaround but isn't a built-in feature for automatic playback, requiring additional steps during the presentation. Therefore, selecting the Play Full Screen option in the Playback Tab is the most efficient and effective approach.
