About mouse dpi:
The mouse DPI (resolution) refers to the positioning accuracy of the mouse, and the unit is DPI or cpi, which refers to the maximum information that can be accurately positioned every inch when the mouse moves.
when we move the mouse one inch to the left, the mouse with 4dpi will send a "move left" signal to the computer 4 times, while the mouse with 8dpi will send it 8 times. Suppose that we move the mouse by 1/8 inch, then the mouse with 8dpi will send a moving signal to the computer, but the mouse with 4dpi will not respond. We have to move it by 1/8 inch to send a moving signal. Simply put, a mouse with 8dpi will respond faster than a mouse with 4dpi at the beginning of movement. The performance difference between 8dpi and 4dpi mice will be obvious only when the display resolution is high
