A smart projector is a modern device that combines traditional projection technology with advanced features like wireless connectivity and built-in applications. It allows users to stream content directly from the internet or connect to devices like smartphones and laptops without needing extra cables. This makes it convenient for presentations, movie nights, and gaming. Many smart projectors come equipped with voice control and smart assistants, enabling users to operate them hands-free. They often support high-definition resolutions and can project images onto various surfaces, making them versatile for both home and professional use.
