🔘 Physical Switch Diagnostic
Mouse DPI Button Test
Verify that pressing your physical mouse DPI switch actually toggles optical sensor resolution across up to 4 distinct hardware stages.
DIRECT SUMMARY
Can a website know when you press your DPI button?
No. Because DPI switching is handled internally by your mouse microcontroller firmware and optical sensor registers without sending a standard OS keycode, websites cannot detect the button press directly. Instead, this test observes pointer displacement changes before and after pressing the button.

Typical DPI Button Presets
Most gaming mice come pre-programmed from the factory with 4 standard preset steps:
- Stage 1: 400 DPI (Red LED indicator)
- Stage 2: 800 DPI (Green LED indicator)
- Stage 3: 1600 DPI (Blue LED indicator)
- Stage 4: 3200 DPI (Purple LED indicator)
Summary & Verification Takeaways
- Websites observe pointer coordinate changes rather than intercepting internal DPI button switch events.
- Swiping 20 cm at each stage reveals whether your mouse changes resolution proportionally.
- If observed counts remain identical between button presses, your DPI button may be disabled or unassigned in companion software.
