Manual projector screens are a cost-effective and practical option for home theaters, classrooms, and small meeting spaces. They are operated by pulling the screen down manually, much like a window shade, and can be retracted when not in use to save space. These screens typically come with a spring-loaded mechanism that allows for smooth extension and retraction. Available in a variety of sizes and aspect ratios, manual projector screens offer a simple setup and reliable performance for users who don't require automated features.
