Understanding DPI: What does DPI mean in a mouse and how does it impact performance?

26 Tem 22:15

I'm trying to grasp the concept of DPI (dots per inch) in a computer mouse. How does changing the DPI setting affect cursor movement and responsiveness? Does a higher DPI always mean smoother tracking, or are there trade‑offs depending on screen resolution or usage scenario? Also, how does DPI interact with polling rate and sensor technology? Looking for a clear explanation of the underlying principles.
