Display Color Banding Test | Check for Gradient Banding

4.84(43 ratings)

Free online color banding test tool. Check your display for color banding, gradient banding, and bit depth issues.

How to use:

  1. Click the "Start Test" button below to enter full-screen mode
  2. Use arrow keys or click anywhere to cycle through different gradient patterns
  3. Look carefully for visible bands or steps in what should be smooth gradients
  4. Check both horizontal and vertical gradients
  5. Test individual RGB channels for specific issues
  6. Click X button or press ESC key to exit full-screen mode

The test includes the following gradient patterns:

Black to White gradient - horizontal

Black to White gradient - vertical

Black to Red gradient - horizontal

Black to Green gradient - horizontal

Black to Blue gradient - horizontal

Full RGB spectrum gradient

Dark gray gradient for subtle banding

Warm color gradient for natural transitions

Test your display for color banding issues by examining smooth gradients. Color banding appears as visible strips or steps in what should be smooth color transitions. This can indicate display bit depth limitations or incorrect color settings.

Frequently Asked Questions

What is color banding?

Color banding is a visual artifact where smooth gradients appear as distinct bands of color instead of blending seamlessly. It is often noticeable in images with subtle color transitions.

How do I test for color banding on my screen?

You can use our Color Banding Test tool to check for banding issues. The tool displays gradient patterns, making it easy to identify any visible bands on your monitor.

What is a color gradient test?

A color gradient test checks how smoothly your screen transitions between colors. It helps identify issues like color banding, which can degrade the quality of images or videos.

What causes gradient banding on screens?

Gradient banding can be caused by limited color depth (e.g., 8-bit instead of 10-bit), poor display calibration, or compression artifacts in images and videos.

How can I fix screen banding issues?

To fix screen banding, ensure your monitor supports higher color depths, use uncompressed or high-quality media, and properly calibrate your display. Upgrading to a monitor with 10-bit color depth can also help.

Why does my monitor show color banding?

Your monitor may show color banding due to limitations in color depth, incorrect display settings, or poor-quality content. Testing with our Color Banding Test tool can help pinpoint the issue.

What is monitor banding, and how can it affect visuals?

Monitor banding refers to visible bands in gradient transitions on your screen. It can make visuals appear less smooth and reduce the quality of images, videos, or graphics.

Can I reduce color banding with calibration?

Yes, calibrating your monitor can reduce color banding by optimizing color settings, brightness, and contrast. Use professional calibration tools or software for the best results.

How does the Color Banding Test tool work?

The tool generates gradient patterns that help identify color banding issues. You can compare the smoothness of gradients on your screen to detect any visible bands.
