I. Is the larger the screen size the better?
Large size projection screens can bring visual and experience shocks to everyone, so many friends are buying projectors. At times, super-sized projection screens are always chosen, so is the bigger the projection screen the better?
In fact, the size of the projection screen is not the bigger the better, but it is better to choose the suitable size. The reasons are:
1. In theory, almost all projectors can provide 100 inch The above picture size, but in fact, due to the difference in the quality and performance of the projector, large-scale projection usually sacrifices some image quality. If the screen is too large, the clarity and contrast of the projection will be reduced; otherwise, choose Projectors and projection screens with higher specifications will be much more expensive and not cost-effective.
2. If the size of the projection screen is relatively large, its radiation area will also be large, and long-term viewing will cause nausea, fatigue and other symptoms of the viewer, and the vision will also decline.
3. The selection of the screen size depends not only on the picture quality, but also on the installation position of the screen. If the area of the wall is not enough, a large screen cannot be installed.
Therefore, although the large-sized screen looks more cool, it should be selected according to the actual situation, so what is the appropriate size of the projection screen?
Second, what is the appropriate size of the projection cloth
The selection of the projection cloth size needs to consider many factors, including projector resolution, brightness, projection ratio, projection distance, viewing distance, installation space size, etc. For most home users, the size of the projection screen set in the living room will generally not exceed 120 inches, and the selection can be based on the viewing distance or indoor area. :
