A 3D monitor is a display device that creates the illusion of depth, allowing viewers to see images in three dimensions. This technology enhances the viewing experience for movies, video games, and simulations by making them more immersive. 3D monitors typically require special glasses to perceive the depth effect, which can be achieved through various methods, such as active shutter or passive polarization. These monitors are used in various fields, including entertainment, design, and education. In gaming, for instance, 3D monitors can provide a more engaging experience, while in medical imaging, they help professionals visualize complex structures. Overall, 3D monitors offer a unique way to experience visual content.
