Por Qué Ocurren las Bandas

Why Should You Run This Test?

If you notice blocky transitions in photos, video playback, or games — especially in sky, shadow, or gradient scenes — your monitor may have color banding. This test quickly tells you whether the issue is your panel or your content.

Common Symptoms

  • Visible "steps" or bands in sunset photos or dark movie scenes
  • Posterization in Photoshop or Lightroom when editing gradients
  • Noticeable banding in game skyboxes or loading screens
  • Colors look "chunky" instead of smooth

What Causes Color Banding?

Hardware Causes

  • 6-bit panel — Budget monitors use 6-bit panels with only 262K colors. Banding is inherent and cannot be fully fixed.
  • 8-bit panel without dithering — Some 8-bit panels skip temporal dithering, reducing effective color depth.
  • Low-quality display cable — A damaged or inadequate cable (e.g., VGA instead of DisplayPort) can reduce color depth.

Software Causes

  • GPU color output set to limited range — Check GPU settings: use "Full" RGB range (0-255), not "Limited" (16-235).
  • Incorrect bit depth in OS — Windows may default to 8-bit even on 10-bit panels. Check display adapter settings.
  • Compressed video streaming — Streaming services compress gradients, causing banding in the source content itself.

How to Read Your Results

✅ Smooth, seamless transitions — Your display handles gradients excellently. Likely an 8-bit + dithering or 10-bit panel. No action needed.

⚠️ Slight stepping visible in dark tones — This is common on 8-bit panels. Enable dithering in your GPU driver settings. Consider calibrating your monitor.

❌ Obvious bands/stripes across the gradient — Your display has limited color depth (likely 6-bit) or there is a configuration issue. Check GPU output settings, cable quality, and whether your OS is sending the correct bit depth.

How to Fix or Reduce Banding

  • Enable 10-bit output — In NVIDIA Control Panel or AMD Radeon Settings, change color depth to 10-bit if your panel supports it.
  • Set RGB range to Full — GPU settings → Display → Output Dynamic Range → Full.
  • Use DisplayPort or HDMI 2.0+ — Older cables limit color depth. Use DisplayPort 1.4 or HDMI 2.0 for full bandwidth.
  • Enable temporal dithering — Some monitors have a dithering option in their OSD menu. This simulates extra colors.
  • Calibrate your monitor — Use built-in calibration tools (Windows: Color Management) or a hardware colorimeter.
  • If banding persists — The panel itself is the limitation. Consider upgrading to a 10-bit display for professional work.

✅ Good Result — Smooth Gradient

You should see a perfectly smooth transition from black to white (and black to red, black to blue) with no visible steps, bands, or stripes. Each tone blends seamlessly into the next like a continuous wash of color.

⚠️ Mediocre Result — Slight Banding

You may notice faint horizontal or vertical bands in the darker portions of the gradient, where tones "jump" slightly instead of blending smoothly. This is typical of 8-bit panels without dithering and is most visible in the dark-to-mid tone range.

❌ Bad Result — Obvious Banding

You see clear, distinct stripes or blocks of color — the gradient looks like a staircase rather than a smooth ramp. This indicates a 6-bit panel, incorrect GPU settings, or a cable that is limiting color depth.
