Pacing and control when the information is revealed.
Good captivating presentations are foremost a spoken medium. You're telling a story. You use the screen as an aid for concepts that are easier to show than to describe, and secondarily as an reinforcement/amplification of the points you're making, and then as a background setting the mood of the talk.
But the visuals have to match what you're talking about. Otherwise they're out of context and distracting by foreshadowing what you're going to talk about next. You also can't emphasise things by making a sudden reveal if the presentation is gently scrolling by itself.
BTW the classic PowerPoint style of long lists of bullet points with the presentation outline is IMHO not good. That's more of an aid for the presenter than the audience.
