In addition, generally speaking, there are a formula: the best visual range = point spacing/( 0. 3 to 0. 8) , this is a general range. Point spacing of 16 mm screen, for example, that the best visual range is 20 ~ 54 meters, standing close than the minimum distance, will be able to discern the display of each pixel of the particles are stronger, stand farther away, the characteristics of human eyes do not know the difference between details.
