1. The proportion of the curtain
There are three types of projector screens: 4:3, 16:9, and 2.35:1. 4:3 curtains are often used in commercial environments, but now the resolution of commercial projectors has reached 1920×1080, so the 4:3 curtains in commercial venues will slowly be replaced by 16:9 curtains. Family purchase projection screen will generally choose 16:9 and 2.35:1, and most families are selected 16:9, 2.35:1 is generally used for villa users with a dedicated audio-visual room, but also for home projectors Use with special anamorphic lenses. Therefore, the 16:9 curtain is the best choice for mainstream home projectors, and is the best choice for ordinary families to use in the living room. 
2. The size of the curtain
The size of the curtain is the same as the size of the flat-panel TV, and it refers to the length of its diagonal. Ordinary family living room theater, the choice of curtain size is generally between 100 to 133 inches, and the specific size will be determined according to the installation position and projection distance of the curtain. If the screen is installed at a length of 3 meters, it can basically be installed with screens under 110 inches. With a length of about 3.5 meters, it can be installed with curtains under 130 inches. Not only the installation position determines the size of the curtain, but also the projection distance of the actual space determines the size of the installation curtain. Because this depends on the actual distance and the specific projector model, there is no fixed number. 
The electric curtain can be lifted and retracted, so it can be applied to various places. The frame can not be recycled, generally only used for fixed places. The picture frame screen is better than the electric screen in terms of service life
The electric screen belongs to electrical products, and the life of the motor is always extremely limited. However, the theoretical life of the frame curtain is far longer than that of the electric screen as long as it does not intentionally destroy the life. Judging from the effect of use, the tension around the picture frame screen is fixed, the flatness is very good, and it can guarantee long-term flatness. The electric curtain is slightly deformed even if it is pulled. If it is not pulled, it will be easily curled. Therefore, my suggestion is that if there is a dedicated audio-visual room or if you do not use a TV in the living room, the frame curtain is the best choice. If you use it in the living room and you need a wall-mounted TV, you have to choose an electric screen. 
4. How to choose the white screen and the gray screen?
The gray screen is often referred to as a "high-contrast screen" because the gray screen absorbs more ambient light than the white screen does. This allows the black level on the screen to be maintained, white on the projection screen remains white, and black is As the interference of ambient light is reduced and it becomes darker, this directly leads to an increase in the black-and-white contrast ratio on the screen, darkness in black, increased contrast, and enhanced three-dimensionality. However, the gray screen also has undesirable side effects. The coating on the surface produces a layer of disturbing lines such as veil. Although the white screen does not have the specific function of a gray screen, it matches the same gain of the gray screen, and the white screen is more transparent and vivid. Although there are advantages and disadvantages, what should we choose? For the average family's living room theater, my suggestion is to choose a white screen with 1.5 gains, which is more applicable. 
5. Household projector screens, like all other commodities, also have high, medium and low grades, ranging in price from a thousand to a few tens of thousands. High-end brands include foreign brands Stewart, kikuchi (Chrysanthemum or Kikuchi), mid- to high-end brands with foreign OS (Oise), domestic Yili, and Meishi, etc., entry-level brands include Hongye, Jingke, etc. .
