Hello,
Thank you for posting in Q&A forum.
In Windows, the pointer speed setting controls the speed of mouse movement, while DPI (Dots Per Inch) determines the distance the mouse pointer moves on the screen. These two settings can mutually affect the performance of the mouse.
Usually, when you increase the pointer speed setting, the mouse movement speed will increase, while reducing the pointer speed will slow down the mouse movement speed. If you set the pointer speed very high, even if the DPI setting of the mouse is low, the mouse will move quickly on the screen. On the contrary, if the pointer speed is set low, even if the DPI of the mouse is set high, the speed of the mouse moving on the screen will slow down.
Regarding the options you provided, they represent different pointer speed options in Windows mouse settings, and their values represent different speed multiples. For example, 1 represents normal speed, 0.5 represents half speed, 2 represents double speed, and so on.
Therefore, you can adjust the pointer speed setting based on personal preferences and usage habits to achieve the most comfortable and effective mouse movement speed on the screen. I hope this can help answer your questions. If you have any other questions, please feel free to let me know.
Best regards,
Jill Zhou
