How to check the current dpi value of the mouse

The easiest way is to check it on the packaging, manual or sticker on the bottom of the mouse; you can also open the driver setting software that comes with the mouse to view and set the DPI of the mouse; also You can calculate the mouse's mobile DPI yourself. The following is a detailed introduction:

1. Use the driver software provided by the mouse manufacturer to view and adjust the DPI;

2. The DPI of the mouse will be marked on the mouse packaging box and promotional webpage; Some mouse DPI will be printed on the bottom of the mouse, and there is a label that says; For an example of actual movement, the mouse DPI can be obtained by dividing the two data; DPI refers to the pixel value in inches, that is to say, if the DPI is 800, the cursor on the screen will move 800 pixels if the mouse moves one inch;

Extended information:

DPI parameter refers to how many "points" the mouse cursor can move on the screen while the mouse moves 1 inch on the desktop.

In fact, the concept of DPI cannot more accurately and uniquely represent the accuracy of the mouse. For example, the "dots" in dots per inch are not constant on the screen. It is affected by factors such as resolution, so it is not the only one that corresponds to the pixels on the screen. It may be that this point is 4 pixels, or it may be 1 pixel. This is because the concept of DPI involves changes in the display.

The more scientific and recognized new standard is to use CPI to express mouse accuracy. The explanation of this concept is: mouse samples per inch. To put it clearly, if the mouse moves one inch, how many points of change can the mouse itself collect from the moving surface.

This attribute is completely related to the performance of the mouse itself and no longer involves the problem of the monitor. Therefore, it can reflect the accuracy of the mouse more accurately and unchanged. But since most mouse manufacturers have adapted to the DPI naming method. Therefore, most of the production links continue to use the DPI indicator representation method.
