How to choose the screen size? This writting will help you find the proper size for you.
The size of the screen is actually related to the size of the living space. If the home theater or living room is relatively large, you can choose a large screen. If the space is small, you can choose a smaller screen. Generally, to watch movies at a distance of about 3-4 meters from the screen, it is more appropriate to brush the screen with a screen of 100-120 inches on the wall. It is more appropriate to choose a screen of 130-150 inches when watching a movie at a distance of 4-5 meters from the screen.
If it is an ultra-short-throw projector, then this distance can be shortened by about one meter, but if it is a reflective ultra-short-throw projector, similar to a special projector such as a laser TV, in fact, 0.4 meters can project 100 inches. Therefore, we must first determine the parameters of the projector lens. As for the ratio, home projectors generally use a 16:9 display ratio. Because the current movies are basically in this ratio, the online playback ratio provided by video websites is also mostly 16:9.
Projection screens with a 4:3 display ratio are mainly used in professional fields such as business and education. The 2.35:1 projection screen is a display ratio with a wide viewing angle. In the high-end home theater of the main user, the general household does not need such a professional ratio. 16:9 can meet ordinary needs.
