Banding (Gradient) Test for Monitors

gradeint test for screen

A gradient test (also known as a color banding test) helps you spot any issues with color transitions on your screen. When you run this test, it shows a smooth range of colors, allowing you to see if your display can handle the transitions without any noticeable lines or “banding.” It’s a quick way to check if your monitor is up to the task of showing colors correctly.

Start the Gradient Tests by clicking the “►” button in the test panel.

This is especially vital for professionals in graphic design, photography, and video production, where color accuracy and visual integrity are paramount. Regular gradient testing helps maintain the quality assurance of digital displays, ensuring that the final content appears as intended across various devices.

Display Banding?

Display banding, often referred to as color banding, is a visual artifact that appears on digital screens as distinct bands or stripes of color, which disrupt the smooth transition in gradient images. This phenomenon occurs when the screen’s color depth isn’t sufficient to render a seamless gradation between shades. It’s most noticeable in dark scenes or when a single color fades into another gradually. The main culprits behind display banding include limited color depth, poor compression algorithms, and suboptimal screen calibration.

Conducting a Gradient Test

Tools and Software Needed

To conduct an effective gradient test, you might use a variety of tools ranging from software applications to dedicated websites. Popular choices include color management and calibration software like DisplayCAL or online resources like alcolorscreen.com that provide test patterns specifically designed for banding detection.

Step-by-Step Guide

  1. Setup: Ensure that your monitor settings are reset to default or to a known calibration profile before starting the test.
  2. Choose a Tool: Select a gradient testing tool or software.
  3. Run the Test: Open the gradient test image or pattern. This usually displays a gradient ranging from black to white or through a spectrum of colors.
  4. Observe: Look carefully at the transitions between colors or shades. Note any abrupt changes or bands where the colors do not change smoothly.
  5. Adjust Settings: If banding is noticeable, try adjusting your monitor’s settings, such as brightness, contrast, or color depth. In some cases, changing the screen resolution or updating graphics drivers may also help.
  6. Re-test: After making adjustments, run the test again to see if there is an improvement. Repeat adjustments as necessary until the gradient appears smooth.
