HubColor Banding Test
Overview

Color Banding Test.

Evaluate monitor color bit depth, gradient smoothness, and GPU dithering quality. Test 8-bit, 10-bit, RGB, and Grayscale smooth gradients.

Execution steps

  1. 01Launch the full-screen color banding gradient test.
  2. 02Select between Grayscale, Red, Green, Blue, RGB, and Rainbow gradient bars.
  3. 03Inspect the gradient transitions from pure black to maximum intensity.
  4. 04Smooth continuous color blends indicate good bit depth; harsh visible vertical lines indicate color banding.

Diagnostic symptoms

  • Step-like vertical bars (banding) caused by 6-bit + FRC panels or improper GPU color output format.
  • Abrupt harsh transitions in dark shadows.
