Drift · 2026-03-02What is stick drift?Stick drift is the stick reporting movement while your thumb is off it. In a browser that shows up as X and Y sitting away from zero.
Repair · 2026-03-04How to fix stick driftWork from the cheapest step that can change the resting number: firmware, deadzone, cleaning, then a new stick module.
Drift · 2026-03-06PS5 stick driftStandard DualSense sticks are potentiometers. The Edge uses replaceable modules. The browser test is the same for both.
Drift · 2026-03-08Xbox stick driftSeries and One sticks are potentiometers. A Hall-effect swap is a repair, not something Windows can detect by name.
Calibration · 2026-03-10DualSense calibrationA calibration write stores a new center. A deadzone ignores the center you already have. They are different tools.
Calibration · 2026-03-12PS4 controller calibrationThe rear pinhole reset reboots the pad. It does not replace a worn stick.
Calibration · 2026-03-14Xbox controller calibrationWindows does not ship a global deadzone for modern Xbox pads. The game or Steam Input does.
Calibration · 2026-03-16What is a controller deadzone?The raw stick and the value after a deadzone are both on the calibration page. The dot is raw. The square marker is what a game would keep.
Calibration · 2026-03-18Steam Input deadzone settingsIf Steam presents your pad as an Xbox 360 device, you are testing Steam until you turn that layer off.
Repair · 2026-03-20PS5 controller repairMatch the repair to the part that failed: stick, trigger, battery, or button.
Repair · 2026-03-22PS4 controller repairThese pads are old enough that a high resting radius is ordinary wear.
Repair · 2026-03-24Xbox controller repairA bumper that never lights is a microswitch. A stick that rests off center is the module.
Repair · 2026-03-26When to replace an analog stickReplace the module when a still sample stays high after firmware and with remappers off.
Connection · 2026-03-28Connect a PS4 controllerThe pad can be paired to the computer and still hidden from this site until you press a button on the tab.
Connection · 2026-03-30Switch Pro not pairing057E:2009 is the usual id. A third-party “Pro” pad often uses a different vendor.
Connection · 2026-04-02Bluetooth controller keeps disconnectingIf the same pad is stable on USB and drops on Bluetooth, the sensor is not the first suspect.
Connection · 2026-04-04DualSense troubleshootingMost “dead” DualSense reports on a website are the browser waiting for a button press.
Connection · 2026-04-06Nacon controller not detectedIf the operating system’s controller list is empty, the website cannot see the pad either.
Performance · 2026-04-08Controller input lagA 4 ms wired age and a 20 ms Bluetooth age is a real difference. A 2 ms gap is noise.
Performance · 2026-04-10Test a controller on PCA browser tester answers whether the computer received the input. It does not replace the OS driver panel or a hardware poll-rate probe.
Performance · 2026-04-12Xbox 360 vibration on PC360 pads are still XInput devices on Windows. The browser can light buttons and, in Chromium, often play dual rumble.
Hardware · 2026-04-14Controller battery lifeThe Gamepad API rarely exposes a trustworthy battery percentage. A slot that drops after an hour may be charge, sleep, or radio.
Hardware · 2026-04-16Hall-effect sticks on PS5-style padsA magnet sensor avoids the carbon track that wears. The browser still only sees the axes.
Hardware · 2026-04-18TMR and Hall-effect sticksBoth designs avoid a carbon track. Neither is visible to the Gamepad API except through how still the center is.
Hardware · 2026-04-208BitDo firmware updatesVendor 2DC8 is the family. The product id changes with X, D, S, and mac modes, and sometimes with firmware.
Compatibility · 2026-04-22HID-compliant game controllerHID-compliant means the pad spoke a standard report. It does not mean the button order matches the W3C standard mapping.
Compatibility · 2026-04-24Which controllers work on which consolesWorking on this website and working on a console are different questions.
Performance · 2026-04-26DualShock vibration in the browserA sent vibration command only proves the browser accepted the call.
Compatibility · 2026-04-28Test a Guitar Hero controllerA guitar controller is a gamepad with a strange shape. The raw list is the right view.
Hardware · 2026-04-30Logitech wheel software and testingA wheel is axes and buttons. The browser can show those. Force feedback is a separate driver path.
