Deadzone tester: measure stick movement

Reset the measurement with the controller untouched, observe the resting radius, then try a deadzone just above the unwanted movement.

Live controller test

Connect a controller and press one of its buttons. You can also try Demo mode.

X: 0.000 · Y: 0.000 · Radius: 0.000

Peak resting radius since reset: 0.000

Illustrative mapped output: 0.000, 0.000

Measure with the stick untouched after resetting. This browser tool uses a simple radial model; it does not change DS4Windows settings. Axis ordering and browser mapping vary by device. Demo readings are simulated.

How to test reliably

Start with one controller and a simple profile. A browser may not expose a device until you press a button with the page focused. If HidHide is active, you may see only the virtual output; that is useful for checking the game-facing path but is not a raw physical measurement.

  1. Connect the controller and press a button.
  2. Choose the intended physical or virtual device from the list.
  3. Test each button once, pull triggers slowly and move both sticks through their range.
  4. For drift, release the stick, reset the measurement and leave the pad untouched.
  5. Compare a baseline profile with your adjusted profile in the actual game.

Read the limits correctly

The Gamepad API reports the mapping exposed by the browser. Axes 0/1 and 2/3 commonly represent left and right sticks for standard mappings; unusual controllers can differ. The reported stick radius can exceed 1 at diagonal corners. Browser axes do not establish USB/Bluetooth report timing, adaptive resistance, microphone function or haptic motor movement. A vibration request is only a request; confirm the physical result.

If no controller appears

Keep this page focused and press a controller button. Check Windows detection, browser Gamepad API support and HidHide visibility. Do not disable browser or operating-system security protections. Demo mode lets you inspect the interface without connecting hardware.
