White Screen Test – Check Dead Pixels & Monitor Quality

White Test Screen Check offers a White Screen Test designed to help you identify display problems like dead pixels, colour tinting, and backlight bleed. Whether you’re using a monitor, phone, or tablet, our tool fills your screen with pure white to highlight inconsistencies.

Why use a White Screen Test?

A white screen makes it easier to detect any non-uniform brightness or pixel defects. Dead pixels appear as small black dots, while backlight bleeding may look like bright patches on the edges. This quick visual test helps assess display quality within seconds.

How to Perform the Test

1. Visit WhiteTestScreenCheck.com.
2. Click “Start Test” to display a pure white screen in full-screen mode.
3. Observe carefully for any colour spots or inconsistencies.
4. Press Esc to exit full-screen mode.

Other Screen Tests

Besides the white screen, you can use other colours to check for different issues:

• Black Test Screen – Detect backlight bleed and glow.
• Green Screen Test – Identify stuck or tinted pixels.

Final Thoughts

Regularly testing your display ensures it maintains visual accuracy, especially for design or video work. With White Test Screen Check, you can quickly identify problems before they worsen.
