Video projection is a technology that allows images and videos to be displayed on a surface, typically a screen or wall. This is achieved using a projector, which takes video signals from devices like computers or DVD players and converts them into light. The projector then casts this light onto the chosen surface, creating a larger visual display. Video projection is commonly used in various settings, including classrooms, business presentations, and home theaters. It enables audiences to view content collectively, making it easier to share information and enhance experiences. The quality of the projection can depend on factors like the projector's brightness and resolution.
