Grayscale

Look for neutral gray without red, green, or blue tint. Each step should remain distinct.

Visual check, not calibration

These patterns can reveal common display issues. Accurate color calibration requires a supported colorimeter and controlled lighting.

Quick start

How to use this monitor test

  1. 1

    Set your display to its normal viewing brightness.

  2. 2

    Open the pattern viewer and enter fullscreen if helpful.

  3. 3

    Move through each pattern and read its guidance.

  4. 4

    Note clipping, tint, banding, or blur without changing several settings at once.

What it checks

Understand the result

  • Grayscale neutrality and gradient banding
  • Shadow and highlight separation
  • RGB color rendering
  • Sharpness, pixel mapping, and viewing-angle changes
Troubleshooting

Common problems

  • Aggressive contrast can hide dark or bright steps.
  • Non-native scaling can blur the sharpness pattern.
  • Color management and room lighting affect visual judgments.

Privacy and browser limits

Most readings come directly from browser APIs and stay on your device. Operating systems, browser permissions, scaling, drivers, and hardware can affect what a page can observe.

For the cleanest result, use an up-to-date browser, keep the tab visible, and close apps that may already be using the device.

FAQ

Questions about the monitor test

Is my test data uploaded?

No. This test runs locally in your browser. RatedTechTools does not receive or store the device data shown by the tool.

Can this calibrate my monitor?

No. Accurate calibration requires a colorimeter. These patterns help with visual inspection and basic settings.

Which pattern should I start with?

Start with grayscale, then black level and white saturation before adjusting color or sharpness.
