How to Use Our Tools
Step-by-step guides to using every Gadgetior tool: what to measure, what each field means and how to read the result.
Every tool, explained
How to use the Mic Test
Press Start, allow microphone access, and talk. The meter moves when your mic picks you up. Record a short clip to hear exactly what others hear on a call.
How to use the Webcam Test
Press Start and allow camera access. You'll see the live picture plus your camera's actual resolution and frame rate, which is often different from what the box says.
How to use the Keyboard Tester
Press every key on your keyboard. Keys turn green once they've been detected, and a key held down shows in color. Any key that never lights up isn't reaching your computer.
How to use the Double Click Test
Click every button inside the test area and roll the scroll wheel. The tool counts each button and warns you if a single click is registering twice.
How to use the Dead Pixel Test
Start the test to fill your screen with solid colors. Look closely at each one. A pixel that stays black, white or one bright color when the rest changes is a bad pixel.
How to use the Speaker Test
Play a tone in the left channel, then the right. If the sound comes from the matching side, your speakers or headphones are wired correctly. Then test bass and the full frequency range.
How to use the Refresh Rate Test
The test measures how often your browser draws a new frame, which follows your screen's refresh rate. It starts on its own. Keep this tab in front while it runs.
How to use the Click Speed Test
Pick a time, then click inside the box as fast as you can. The timer starts on your first click. Your best score for each length is saved on this device.
How to use the Reaction Time Test
Click the box to start. It turns red. Wait, and when it turns green, click as fast as you can. Do five tries for a fair average.
How to use the My Device Specs
Here's what your browser can see about this device right now. Nothing to install and nothing to send. Copy the list if a support agent asks for your system details.
How to use the TV Size & Viewing Distance Calculator
Enter the distance from your seat to where the TV will be. You'll get a recommended size and the closest you can sit before you'd notice pixels.
