How to install the rear projection screen

The screens are installed differently and the screen requirements are different. Telescopic screens are required to be soft materials. The fixed installation has a soft screen and also has a hard screen. The height of the screen is different from the ground installation, and the vertical viewing angle of the screen is also required. The soft rear projection screen and the diffuse reflection screen have a large vertical angle of view. Fresnel optical screens have a vertical viewing angle of only 8-12 degrees, so please pay attention when installing. The vertical tilt angle of a hard screen is generally less than 15 degrees.
