Solid-color display check
Use several colors because different pixel faults are easier to see against different backgrounds.
Look for pixels that remain bright, dark, or the wrong color. Also inspect brightness uniformity near edges and corners.
Inspect your screen with solid colors
Open solid colors in full screen to look for stuck pixels, dead pixels, uniformity problems, and view display details.
How to use Screen and dead-pixel test
- 01Clean the display and choose a solid test color.
- 02Inspect the full screen from a normal viewing distance for pixels that do not match the color.
- 03Press Escape, then repeat with the remaining colors.
Device test questions
Does PetexSpace record my camera or microphone?
No. The camera and microphone tests attach the selected media stream directly to the page in your browser. The test does not upload or save that stream.
Why does a test show different information in another browser?
Browsers and operating systems expose different device details. A missing value means the browser did not make that detail available to the page.
Can a browser test prove that hardware is perfect?
No. These checks help reveal common input, output, pixel, and timing problems. Hardware faults can still require operating system tools or professional diagnosis.
