A presentation screen is a flat surface used to display visual content during presentations, meetings, or lectures. It can be a physical screen, like a whiteboard or projector screen, or a digital display, such as a monitor or television. The purpose of a presentation screen is to enhance communication by allowing the audience to see images, text, and videos clearly. These screens are often used in conjunction with presentation software like Microsoft PowerPoint or Google Slides. They help presenters convey information effectively, making it easier for the audience to understand complex ideas and engage with the material being presented.
