Color Depth Checker
This tool reads what the browser and OS report about color depth and related features. Results are best-effort — some platforms expose limited information to browsers.
screen.colorDepth and screen.pixelDepth, test CSS media features like color-gamut and dynamic-range, and perform a small canvas sample to detect whether the display appears to support >8-bit channels. This provides a best-effort estimate — completely accurate detection of native panel bit-depth is not always available to browsers.
What Is Color Depth?
Color depth (also known as bit depth) refers to the number of bits used to represent the color of a single pixel. Higher color depth allows a device to display more colors with better accuracy, smoother gradients, and less banding.
Common color depths include:
- 8-bit — 16.7 million colors (standard displays)
- 10-bit — 1.07 billion colors (HDR displays)
- 12-bit — Up to 68 billion colors (professional monitors)
Most modern screens support at least 24-bit color (8 bits per channel), while high-end HDR displays support 30-bit or more.
Why Color Depth Matters
Color depth affects how realistic and smooth images appear. It influences:
- Smoother gradients with fewer visible bands
- More accurate color reproduction
- Better support for HDR content
- Professional photo and video editing quality
- Overall display vibrancy and realism
Higher color depth is especially important for designers, photographers, gamers, and anyone viewing HDR content.
What a Color Depth Checker Detects
Our Color Depth Checker typically identifies:
- Your display’s color depth (bits per pixel)
- Whether your display supports 24-bit, 30-bit, or higher
- Browser-reported color capabilities
- Compatibility with HDR displays
Because browsers report color depth differently, a Color Depth Checker helps verify real-world support for modern color standards.
Why Use a Color Depth Checker?
You may want to check your color depth to:
- Verify HDR compatibility
- Ensure accurate colors for design or editing
- Check monitor capabilities before upgrade
- Test browser and system color support
- Diagnose issues like color banding
