Step 1 of 6
Display & Pixel Inspection
Inspect the test color swatches below. Look for black dead dots on white/color backgrounds, or bright stuck subpixels on black.
White Screen
Did you observe any stuck or dead pixels?
Step 2 of 6
Stereo Speaker & Audio Output
Play the audio tones below to confirm left and right channel stereo separation without crackling or distortion.
Left Channel
440 Hz Pure Sine Tone
Right Channel
440 Hz Pure Sine Tone
Did both left and right speakers produce clear audio?
Step 3 of 6
Microphone & Audio Input
Grant temporary microphone permission to verify your input hardware receives sound waves.
Awaiting Activation
Input Volume-∞ dBFS
Speak or clap near your device to test audio input levels.
Did your microphone register sound?

How to understand your result
Looks good: All tested hardware subsystems responded normally during the guided check.
Troubleshooting: what to try next
You can skip any individual test at any time during the wizard.
Unsupported tests are marked 'Not Available' rather than 'Failed'.
No. We deliberately do not assign an arbitrary percentage or fake score. We provide an honest itemized count of tests completed, passed, or needing review.
