Six-Step Fullscreen Monitor Color Test

Test Your Monitor in Six Simple Steps

This six-step fullscreen monitor color test helps you evaluate your display's performance. By cycling through black, white, red, green, blue, and gray screens, you can identify dead pixels, color accuracy issues, backlight bleeding, and uniformity problems. Each color fills the entire screen, making it easy to spot any anomalies.

How the Test Works

  1. Black screen: Check for dead pixels (bright spots) and backlight bleed.
  2. White screen: Look for dark spots, dust, or uneven brightness.
  3. Red, green, blue screens: Verify color accuracy and check for stuck pixels (pixels that don't change color).
  4. Gray screen: Evaluate grayscale gradients and color banding.

Tips for Accurate Testing

Black Screen provides this test for free, with no downloads or registration. Use it regularly to keep your monitor in top condition.
