What does the mouse dpi mean?

The dpi of the mouse is the dots per inch, which is the number of points that the mouse moves on the screen every inch of the pointer. For example, 400DPI mouse, when he moves an inch, the pointer on the screen can move 400 points.

Precision

In fact, the concept of DPI can not be more accurate only to represent the accuracy of the mouse. For example, the dots in dots per inch are not constant on the screen. He is affected by such factors as resolution, so it is not the only pixel on the screen. It is possible that this point is 4 pixels, or it may be 1 pixels. This is because the DPI concept involves changes in the display. The current scientific and accepted new standard is to use CPI to represent the accuracy of the mouse. This concept is explained by: The number of mouse samples per inch. To be clear, is the mouse to move an inch, the mouse itself can be collected from the mobile surface of the number of points of change. This property is completely related to the mouse's own performance, no longer involved in the problem of the monitor. So, the accuracy of the mouse can be more accurate and invariable. But since most mouse manufacturers are now adapting to the DPI address style. So at present, most of the production process also continues to the DPI indicator presentation.

When we need the mouse to move a fixed distance on the screen, the high DPI mouse moves at a shorter physical distance than the low dpi mouse. The former can react to smaller operations in the quickest possible time. Master in order to pursue the maximum stability of shooting, usually the mouse speed preset is very low. When you need to suddenly turn around, 400DPI will use more than 800DPI of physical displacement, so easy to kill the first time the enemy's chance to miss. The high DPI advantage can provide near-perfect precision as well as instant acceleration, while a low-dpi mouse does not do that anyway.

If you want to define the DPI as precision, the high DPI mouse must be positioned more accurately than a low dpi mouse in a fast move. But the dpi of the mouse is not the same, and it does not always hold up to 800 dpi metrics. When the mouse moves at a slower rate, the DPI value becomes very low. The DPI value increases as the movement speeds up. That is, the DPI and mouse are moving in direct proportion to each other. All of this depends on the precise judgment of the optical sensor on the speed of the movement. Now many of the mouse has reached the 4000DPI or even 6000DPI, and there is the function of switching dpi, can actively switch the DPI.
