Frequently asked questions
Does this tool record or store my microphone audio?
No - the mic test only reads the live input level to display on screen; nothing is recorded, saved, or sent anywhere.
Why do dead pixels only show up on certain colors?
A stuck or dead pixel may only be visibly wrong against specific background colors - testing against solid red, green, blue, black, and white in turn reveals pixels that a busy desktop background would hide.
Will my browser ask for microphone permission?
Yes - your browser will prompt for microphone access before the mic level test can run; you can deny it and still use the screen/dead-pixel test independently.
