Color banding is a visual artifact that appears as visible steps or bands in smooth color gradients on your screen, display, or monitor. Instead of a seamless transition between colors, you'll see distinct lines separating different color shades.
What Causes Color Banding?
- Limited Color Depth: Most displays use 8-bit color (16.7 million colors). Cheaper displays may use 6-bit color (262,000 colors) which causes more banding.
- Poor Display Calibration: Incorrect gamma, brightness, or contrast settings can make banding more visible.
- Low-Quality Content: Images or videos compressed with low bitrates can introduce banding.
- Display Panel Quality: Lower quality panels have difficulty displaying smooth gradients.
How to Test for Color Banding
- View the gradient patterns above in fullscreen mode
- Look closely for visible lines or steps in the gradient
- Test in a dimly lit room for best results
- Check from different viewing angles
- Compare with other displays if possible
Can You Fix Color Banding?
While you can't fix hardware limitations, you can reduce the visibility of banding:
- Calibrate your display properly
- Use high-quality content sources
- Ensure your graphics card is set to 8-bit or higher color depth
- Consider upgrading to a higher quality display
