About mouse DPI:

Mouse DPI (resolution ) refers to the positioning accuracy of the mouse. The unit is dpi or cpi. It refers to the maximum number of information that can be accurately positioned per inch of mouse movement when the mouse is moving.

When we move the mouse one inch to the left, a 400dpi mouse will send a "left move" signal to the computer 400 times, while an 800dpi mouse will send 800 times. Assume that if we move the mouse 1/800 inch, then the 800dpi mouse will send a movement signal to the computer, but the 400dpi mouse will not respond. We must move another 1/800 inch before it will send a movement signal. Simply put, an 800dpi mouse will respond faster than a 400dpi mouse at the beginning of movement. The performance difference between 800dpi and 400dpi mice will only become more obvious when the monitor resolution is high.
