Color Test - Check your Display

Check Your Display

The Color Test is a simple online tool that helps you check your monitor’s color accuracy, brightness, contrast, and display issues. It’s useful for detecting dead pixels, backlight bleeding, and color banding, ensuring your screen performs at its best.

How It Works

Solid Color Test

This test displays full-screen solid colors (red screen, green screen, blue screen) to help identify display issues:

• Dead Pixels – Small black or colored dots that don’t change with the screen.

• Color Accuracy – Helps verify if colors appear as expected without distortion.

• Backlight Bleeding – Light leakage from the screen edges, especially visible on black screens.

Gradient Test

This test displays smooth color transitions from dark to light shades:

• Detects Color Banding – If you see visible steps instead of a smooth gradient, your display has poor color depth (Use https://allcolorscreen.com/gradient-tests-for-screen/ ).

• Checks Panel Quality – High-quality screens should show a seamless transition without sudden shifts.

Brightness & Contrast Check

This test helps you fine-tune your display settings:

• Brightness Levels – Ensures dark and bright areas are properly balanced.

• True Color Representation – Adjust your contrast to avoid washed-out or overly dark areas.

• Shadow & Highlight Details – Make sure you can see both dark and bright details clearly.

Dead Pixel Detection

Dead pixels are tiny stuck or non-working dots on your screen. This test helps you:

• Identify Stuck Pixels – Pixels stuck on one color (check this test https://allcolorscreen.com/defective-pixels-test/).

• Find Completely Dead Pixels – Black or white dots that never change color.

• Verify Panel Health – Frequent dead pixels might indicate a defective display.
