What is a white screen tool and why do I need it?

A white screen tool generates solid color displays for monitor testing and calibration. It's essential for detecting dead pixels, testing color accuracy, calibrating brightness, and identifying display issues. Professional photographers, designers, and gamers use these tools to ensure optimal display performance.

How do I test for dead pixels using this tool?

To test for dead pixels: 1) Select a solid color (white, black, red, green, blue); 2) Enter fullscreen mode; 3) Look carefully across the entire screen for pixels that don't match the background color; 4) Dead pixels appear as black dots on colored backgrounds or colored dots on black backgrounds; 5) Test with multiple colors for comprehensive detection.

What's the difference between dead pixels and stuck pixels?

Dead pixels are completely non-functional and appear black on all colors. Stuck pixels are partially functional and display a single color (usually red, green, or blue) regardless of the intended color. Stuck pixels can sometimes be fixed with pixel fixing techniques, while dead pixels are permanent hardware failures.

How do I calibrate my monitor using color screens?

For basic calibration: 1) Use white screen to adjust brightness - it should be comfortable without being too dim or bright; 2) Use black screen to adjust contrast - you should see pure black without gray tinting; 3) Use red, green, and blue screens to check color accuracy; 4) Compare colors with reference standards if available; 5) Adjust monitor settings accordingly.

What resolutions are supported?

We support multiple resolutions: Auto (matches your browser window), 1080p (1920×1080), 4K (3840×2160), 720p (1280×720), 1440p (2560×1440), and custom resolutions. The tool automatically adapts to your display capabilities and provides optimal quality for testing.

Can I use this tool for screen burn-in testing?

Yes, this tool is excellent for burn-in testing. Display solid colors for extended periods to check for image retention or burn-in. Use white or light colors to reveal burn-in shadows, and dark colors to test for bright spots. However, avoid leaving static images on OLED displays for too long as this can cause burn-in.

How do I download color screens for offline use?

Click the 'Download' button to save the current color screen as a high-quality image file. You can then use these images offline for monitor testing, as desktop backgrounds, or for other applications. The downloaded images maintain the selected resolution and color accuracy.

Is this tool suitable for professional color work?

While this tool provides accurate color generation, professional color work requires calibrated monitors and color management systems. Use this tool for basic testing and calibration, but for critical color work (professional photography, print design), invest in hardware calibration tools and color-managed workflows.

Common Issues & Solutions

Fullscreen not working?

Some browsers require user interaction. Try clicking the fullscreen button instead of using keyboard shortcuts.

Colors look different on different devices?

This is normal. Each display has different color profiles. Use this tool to identify and calibrate these differences.

Found dead pixels?

Dead pixels are hardware defects. Check your warranty - many manufacturers replace displays with dead pixels.

Screen burn-in detected?

For OLED displays, try pixel refresher tools. For LCD displays, burn-in is usually temporary image retention.
