Device tests

Screen Test
Test any monitor, laptop or phone screen for dead pixels, backlight bleed, uniformity and banding with a guided full-screen check and a plain-language summary.
Dead Pixel Test
Find dead, stuck and bright pixels on any screen with nine full-screen colours, mark them and compare the count with the usual warranty tolerance.
Screen Color Test
Check your screen for colour tint, banding, lost detail in dark and bright tones, gamma and wide colours, or show any colour full screen.
Refresh Rate Test
Measure the refresh rate your screen really runs at in your browser (60, 120, 144 Hz and more), find the closest standard rate and count skipped frames.
Screen Resolution Test
See your real screen resolution, scaling, window size and pixel density, and check that your screen runs at its native resolution.
Keyboard Test
Test every key of your keyboard online: detect dead keys, key chatter and ghosting, and check how many keys work at the same time.
Mouse Test
Test every mouse button and the scroll wheel online, detect unwanted double clicks from a worn switch and estimate the polling rate. Nothing to install.
Click Speed Test
Measure your clicks per second over 1 to 60 seconds, see your fastest second and your rhythm, and spot clicks that no hand can make.
Gamepad Test
Test your PS5, Xbox, Switch or PC controller online: every button, triggers, stick drift with the dead zone to set, stick range and vibration.
Touch Screen Test
Find dead zones on a phone or tablet touch screen and check how many fingers it detects at once with a full-screen multitouch test.
Microphone Test
Test your microphone online: live level, a voice and background noise check, then record a clip and play it back. The audio never leaves your device.
Speaker Test
Test speakers and headphones online: left and right channels, stereo balance, frequency sweep and white noise to reveal rattles.
Audio Frequency Test
Tone generator and frequency test: exact tones from 20 Hz to 20 kHz, sweeps, WAV files, and checks of the deepest bass and highest tone you hear.
Webcam Test
Test your webcam or phone camera online: live picture, real resolution, measured frame rate and a lighting check. The video never leaves your device.
Vibration Test
Test your phone's vibration motor online: a 30-second guided check of strength, short taps and steadiness, plus patterns and your own rhythm.
Sensor Test
Test your phone's accelerometer, gyroscope and compass online: live values, a bubble level, and guided checks of gravity, drift, movements and heading.
