II. Key Points for Selection 1. Projection Technology Firstly, it's important to understand the projection technology of a projector. Currently, there are three main technologies in the market: LCD, DLP, and LCOS. LCD technology has a high color reproduction rate and is suitable for displaying color-rich content; DLP technology has high brightness and contrast and is suitable for use in bright environments; LCOS technology has a longer lifespan and a smaller size. You can choose the appropriate projection technology based on your actual needs and budget. 2. Resolution Resolution is one of the key performance indicators of a projector. A high-resolution projector can present a clearer image, which is crucial for users who need to display detailed data and graphics. You can choose a resolution that meets your needs, such as SVGA, XGA, WXGA, etc. 3. Brightness and Contrast Brightness and contrast determine the projector's performance in various light conditions. Generally, the higher the brightness, the better the projection effect, but excessively high brightness may lead to unnecessary energy consumption and cost. Contrast determines the sense of light and shade in the picture, which is essential for displaying color-rich images. You need to choose an appropriate brightness and contrast based on your actual usage environment and needs. 4.
