Xbox controller calibration
Windows does not ship a global deadzone for modern Xbox pads. The game or Steam Input does.
What to check first
Update firmware in the official Accessories app, then open the Xbox tester and sample both sticks. A number that only looks centered inside Steam is Steam’s deadzone, not the hardware. Retest with that layer off.
- USB gives the cleaner sample.
- Elite curves live in the Accessories app, not in this page.
- Copy the suggested deadzone into the game if the radius is borderline.
Confirm the reading on the live tester before you buy parts or change firmware. The number on that page is what your browser actually receives.
A practical next step
Repeat the same test after each change and write the resting radius down. A fix that does not move that number did not fix the sensor. If the offset stays above about 0.12 with your hands off the sticks, plan a module replacement rather than another software pass. Model notes live in the controller library.
Frequently asked questions
Does this page change my controller?
No. GamepadTesters only reads the Gamepad API in your browser. Calibration writes, firmware updates, and stick swaps happen in the maker’s tool or at a repair bench.
