Nouplo

Device tests

Every test on Nouplo for checking hardware and reflexes in one place: keyboards, mice and gamepads, screens, microphones, cameras and speakers, and typing, reaction and memory tests. They run in your browser, with nothing to install.

Keyboard, mouse and gamepad

⌨ Keyboard test Press every key — see which ones work. ⊠ Keyboard ghosting test Hold keys together and see which ones your keyboard drops. ⌖ Mouse test Click, scroll and move — see what your mouse really sends. ⌖ Mouse polling rate test How many times a second your mouse reports to the computer. ⇹ Mouse DPI test Move the mouse a known distance and see how many counts it reports. ◎ Click speed test Clicks per second, measured — and every mouse button checked. ⊡ Gamepad test Press any button on your controller to start.

Screen tests

▣ Dead pixel test One colour at a time, edge to edge, to find the pixel that isn’t right. ≋ Refresh rate test How many times a second your screen really updates. ☝ Touch screen test Paint every cell — the ones that don’t respond show up red. □ White screen A full-screen white light — or any colour — in one click. □ Black screen A plain full-screen black, in one click. □ What is my screen resolution? Your screen, your browser window and your refresh rate, measured on the page. ─ Online ruler Real size on any screen — calibrated with the card in your wallet.

Microphone, camera and speakers

● Converters Mic test Is your microphone working? Find out in five seconds. ● Converters Webcam test See yourself as the call will — before the call. ◖ Converters Speaker test Is left on the left? Check speakers and headphones in seconds. ◔ Converters Decibel meter How loud is it? Measure the noise in dB(A) with your microphone. ∿ Converters Hearing test How high can you hear?

Typing, reaction, memory and colour vision

⌨︎ Typing test How fast do you type? Start typing — the clock starts with the first key. ⌨︎ Typing practice Touch typing, one row at a time. The keyboard shows the next key. ␣ Spacebar counter Space bar presses counted, timed and rated. ◎ Jitter click test Jitter clicking, timed — with the gap between every click charted. ◎ Butterfly click test Two fingers, one button — your butterfly clicks per second and rhythm. ↯ Reaction time test Wait for it… now! ⊕ Aim trainer Click, flick and track — warm up your aim in 30 seconds. ❖ Memory test How many digits, squares and positions can you hold in mind? ❖ Sequence memory test Watch the squares light up, then repeat the pattern. ◍ Colour blindness test Twelve dot plates and a colour-matching game — a quick screening, not a diagnosis.

Frequently asked questions

Is anything I type or record sent anywhere?
No. Key presses, clicks and touches are read in the page and go nowhere, and a microphone or webcam test keeps the sound and picture in your browser’s memory, gone when you close the page.
Why does the microphone or camera test ask for permission?
A browser lets a page use them only after you allow it. If you said no by mistake, allow it again from the icon in the address bar and reload the page.
Can a web page test everything?
Not quite. The Fn key never reaches a web page and a few shortcuts are taken by the system first, and a mouse’s DPI or polling rate is measured from the movement the browser sees, so treat those results as a good estimate rather than a lab reading.
Is the colour vision test a diagnosis?
No. It is a quick screen on your own screen, whose colours vary; it can suggest a colour vision difference, but only an eye care professional can tell you for certain.
