OPGW 13313 Business 1080p Projector

The 1080P high-definition projectors on the market can be roughly divided into three grades: high, medium, and low. The low-end products are mainly aimed at the entry-level market. In terms of performance, they can fully meet the needs of watching various HD videos. In terms of adjustment, it tends to be simpler, mainly to allow entry-level users to quickly set up the projector, but the contrast of such projectors is generally not very high, and the overall picture effect is relatively general; mid-range projectors mainly have certain projector knowledge. , the projection picture also has a better performance, the most important contrast of the cinema projector has also been greatly improved, the projector adjustment tends to be more professional, and it is also equipped with various additional functions to improve the projection effect; high-end products are Mainly aimed at enthusiast players, both price and performance are the symbol of flagship. For commercial use, in addition to satisfying home entertainment applications, 1080P high-definition standard projectors can also support clear and delicate text and table content projection for business office applications that often conduct office text, PPT presentations, and video presentations. .
