Presentation screens are large displays used to showcase visual content during meetings, lectures, or events. They can be found in various formats, including LCD, LED, and projector screens, and are designed to enhance the visibility of presentations, videos, and images for an audience. These screens often connect to devices like laptops or tablets to project information clearly. Many modern presentation screens also support wireless connectivity, allowing users to share content without physical cables. This technology is widely used in educational institutions, corporate environments, and public speaking events to facilitate effective communication.
