—— bit Browser reportGamma patterns compare a fine spatial mixture with a solid reference tone. They can help you notice a broad tonal mismatch while keeping the limits of a visual comparison in view.
View the stripe comparison at 100% browser zoom and an appropriate distance so the fine pattern blends together. Scaling, sharpening and the display's pixel arrangement can change the result. Compare more than one reference patch before adjusting a setting.
After a tonal adjustment, revisit near-black and near-white detail. Making one reference look closer can also hide detail elsewhere in the image. Keep a record of your starting settings and make small, reversible changes while comparing normal content.
The pattern uses calculated reference values; it does not measure the display's emitted luminance or complete transfer function. A visual match is influenced by viewing conditions and rendering. Use suitable measurements when a particular gamma or transfer-function target is required.

Patterns support visual inspection. Quantitative color accuracy, brightness, gamut coverage and response time require appropriate instruments and methods.
No. It provides display test patterns and browser information. Screen anomalies that persist at the same position need visual inspection and, when needed, professional assessment.
