Touchpad & Touchscreen Tester

Open the test on your computer, choose Touchpad, and follow eight guided items: cursor movement, left click, right click, tap response, double click, vertical scrolling, horizontal scrolling, and supported pinch input. Use the touchpad you want to check; a browser may receive a mouse and a touchpad in the same way.

Yes. This browser tool is free and requires no account or installation. Diagnostic input and results are processed on the page. You need a working browser and access to the input device; the tool cannot repair drivers or turn a disabled touchpad on.

Follow the left-click, right-click, tap, and double-click prompts. The page records click responses and available timing details. A tap can arrive as an ordinary click, so receiving a click does not independently prove that a physical tap occurred. Compare the result with your intended action.

You can check vertical and horizontal wheel input while using two-finger scrolling on your touchpad. The page records the received direction and event count and moves a visual marker inside the test area. It cannot independently verify the physical finger count or read your natural-scrolling setting.

It checks the signals the browser delivers. Touchpad mode can receive Ctrl-modified wheel input or supported gesture events; these are not proof of a physical touchpad pinch. Touchscreen mode compares the distance between received contacts. The operating system or browser may handle a gesture before the page can observe it.

No. Operating-system gestures such as application switching, desktop switching, and three- or four-finger swipes are outside this test. The touchscreen may report multiple contacts, but the highest count received by this page is not a certified hardware contact limit.

Yes, on a compatible touchscreen PC. Choose Touchscreen and touch the screen directly. The course checks touch response, nine requested positions, a short tap, touch and hold, dragging, simultaneous contacts, two-finger movement, and supported pinch input. A touchpad or mouse cannot substitute for direct screen contact in these checks.

Yes. Touchscreen mode displays the simultaneous contacts received by the browser. Try two fingers together and compare the count with your actions. Missing contacts can reflect browser or operating-system handling, and the observed maximum does not establish your screen’s hardware specification.

Check that the touchpad is enabled in operating-system settings and any laptop-specific function-key control. Place the cursor inside the test area and try the requested action. Compare another browser or application and check whether connecting an external mouse disables your touchpad. An undetected input alone does not prove a hardware fault.

Not reliably from these events. A touchpad can produce mouse-type pointer and click events. The test therefore asks you to use the touchpad and describes only the signals it receives. It does not identify the physical source from a mouse pointer type.

You can try Touchpad mode in a compatible desktop browser on a Mac. Scrolling, pinching, and event timing can differ by browser and settings. This is not a guarantee for every Mac or browser, and operating-system gestures and touchpad force sensing are not tested.

Touchscreen mode is intended for compatible PCs, including Windows touchscreen laptops and convertible computers. The browser must deliver touch or pen pointer events. If screen input is missing, check the hardware specification and operating-system recognition, then compare another application or browser.

No. The diagnostic app is intended for computers and blocks recognized smartphone and tablet environments. A responsive guide does not imply mobile diagnostic support. Use a computer with the touchpad or touchscreen you want to check.

No. It records browser-received input and your own observations. It does not repair drivers, change device settings, calibrate hardware, or determine the cause of a fault. If the symptoms persist outside the browser, compare official settings and support guidance for your computer.

Diagnostic coordinates, event details, observations, and results stay in page memory. The app does not upload them or use a translation service. Language and appearance preferences may be saved locally. Copy results writes text only when you choose that action. Ordinary page and site resource requests are separate from diagnostic input.
