EIZO Monitor Test

Run the EIZO Monitor Test when you want a quick calibration sanity check. It is a free, browser based tool that walks you through test patterns for defective pixels, uniformity, gamma, gradients, sharpness and color distances. The interface is simple: toggle the checks you need, follow the onscreen setup tips, and eyeball the results so you know what to fix before a review.

The test patterns are the practical stuff you actually use. There are black and white pixel checks, uniformity patches for backlight issues, gradient ramps to spot banding, and color distance screens to see if near tones separate. The sharpness and viewing angle tests help confirm type and UI rendering. Treat it like a fast calibration pass that flags problems you can act on, not a final color grade.

Heads up on limits and the win. It is optimized for EIZO monitors but works on any panel and is perfect for preflight checks and side by side comparisons. It is not a replacement for a hardware calibrator when you need absolute proof, but it will catch the stuff that trips you up when you know something looks off.
