Problem

The Corsair Harpoon Wireless Mouse comes with preset DPI (dots per inch) levels, which determine cursor speed and sensitivity. If the DPI isn’t adjusted to your preference, movement may feel too slow for gaming or too fast for precise work.

Solution

You can adjust the DPI on the Corsair Harpoon using the DPI button on the mouse or by creating custom DPI levels in Corsair iCUE software.

Step-by-step instructions

Method 1: Using the DPI button (on-the-fly adjustment)

  1. Locate the DPI button behind the scroll wheel.
  2. Press the button to cycle through preset DPI levels (commonly 400, 800, 1600, 3200, and 10,000).
  3. Watch the LED indicator — it changes color to show which DPI stage is active.
  4. Test movement until you find the speed that feels comfortable.

Method 2: Using iCUE software (custom DPI settings)
5. Connect the mouse to your PC and open the Corsair iCUE software.
6. Select the Harpoon Wireless Mouse from the device list.
7. Go to the DPI tab.
8. Add or adjust DPI stages to your preferred sensitivity (up to the mouse’s max DPI).
9. Assign custom colors to each DPI stage for easy recognition via the LED.
10. Save the profile and apply it to the mouse.

Optional methods or tools

  • Onboard memory profiles: Save DPI settings directly to the mouse for use without iCUE.
  • Sniper button remap: Reassign a button to temporarily lower DPI for precision aiming.

Best practices or tips

  • Lower DPI (400–800) is best for precise aiming in FPS games.
  • Higher DPI (1600–3200) works well for general use or fast movement in MOBAs/MMOs.
  • Extremely high DPI (5000+) may feel too sensitive unless paired with a large, high-resolution monitor.
  • Test DPI levels in-game to fine-tune sensitivity for different playstyles.
