The integrated retractable projector screen is easy to use and requires no installation. It can be easily pulled out for use by pulling the metal pull ring, and comes with a storage strap for easy storage and portability.
The projection screen is made of high-quality white fiberglass, which provides clear 4K high-resolution images with rich colors to protect eyes from fatigue, and is thick, smooth, and wrinkle-free.
The projection screen has a 170° wide viewing angle and uses standard black backboard material to prevent light penetration; the four-sided black border design improves image contrast and absorbs light deflection to ensure the highest quality video images.
The projection screen is designed with a high-strength aluminum alloy shell to protect the screen. The reinforced aluminum tube serves as a support shaft, which is stable and durable. The bottom support feet allow the screen to stand on any type of flat ground or table.
The projection screen can be placed anywhere indoors or outdoors, including living rooms, gardens, backyards, classrooms and offices, allowing you to enjoy clear pictures with family and friends.
