Create a pure white image in common resolutions or custom dimensions and export it in PNG, JPG, WebP or SVG.
Why this test is useful
The generated file has the selected digital dimensions and color value, but another display can still show that white differently because of color management and panel characteristics. After download, verify the saved dimensions and format in the file properties before using it in a production workflow.
Before you start
- Use the display native resolution when possible and keep browser zoom at 100 percent so fine patterns are not rescaled.
- After download, verify the saved dimensions and format in the file properties before using it in a production workflow.
- The generated file has the selected digital dimensions and color value, but another display can still show that white differently because of color management and panel characteristics.
A reliable way to run the test
- The generated file has the selected digital dimensions and color value, but another display can still show that white differently because of color management and panel characteristics.
- After download, verify the saved dimensions and format in the file properties before using it in a production workflow.
- This is a visual reference, not color calibration. Accurate calibration requires measurement hardware and a controlled color workflow.
- After an artificial pattern reveals something, check the same area with real photos, video or games at your normal viewing distance.

What this test cannot prove
This is a visual reference, not color calibration. Accurate calibration requires measurement hardware and a controlled color workflow. The test itself runs in the browser. Hosting, analytics or advertising can still make ordinary network requests if the site owner enables them. Do not make a hardware decision from one pattern alone. Repeat the observation with a second pattern or related test.
