5.2 Adjusting DPI Sensitivity
The PERIMICE-222PB mouse offers three adjustable DPI (Dots Per Inch) settings: 1200, 1600, and 2000. DPI determines how sensitive the mouse is to movement. A higher DPI means the cursor moves further with less physical mouse movement.
- To change the DPI setting, press the dedicated DPI button located just below the scroll wheel.
- Each press will cycle through the available DPI settings (1200 → 1600 → 2000 → 1200...).
- Select the DPI setting that best suits your preference and task.
