The meaning of each item in the settings:

Contrast: it is the ratio of black to white, that is, the gradual change of black and white. The greater the ratio, the more layers from black to white, and the richer the color performance. There are two contrast testing methods in projector industry. One is the full-on/full-off contrast test, that is, the brightness ratio of the full white screen and the full black screen output by the projector is tested. The other is ANSI contrast, which is tested by ANSI standard test method. The ANSI contrast test method uses 16 black and white blocks, and the ratio of the average brightness of eight white areas to the average brightness of eight black areas is the ANSI contrast. The contrast values obtained by these two measurement methods are quite different, which is also an important reason for the great difference in the nominal contrast of products from different manufacturers.

Sharpness: the so-called sharpness, also called "sharpness" in some places, is an index reflecting the sharpness of image plane and edge. If the definition is increased, the detail contrast on the image plane is also higher and looks clearer. For example, in the case of high definition, not only the wrinkles and spots on the face on the screen are clearer, but also the protrusions or depressions of facial muscles can be lifelike. On the other hand, dark lines or black lines in the vertical direction, or places where black-and-white images suddenly change, in the case of high sharpness, the edges of lines or black-and-white images suddenly change more sharply, and the overall picture appears clearer. Therefore, improving sharpness is actually improving clarity, which is the good side that people need.

Saturation: it is one of the elements of color, and it is also one that photographers attach great importance to. Below, we will make a comprehensive discussion on the problem of saturation. ? Actually, it refers to the purity of color. The higher the purity, the brighter the performance, and the lower the purity, the darker the performance. In English, saturation and chroma talk about the same thing. ?
