Run a set of browser-based monitor test patterns for colors, grayscale, gradients, contrast, sharpness, and display uniformity.
Switch between solid colors and structured patterns to inspect pixels, banding, tint, scaling, and visible panel inconsistencies without installing software.
Grayscale steps reveal crushed shadows, clipped highlights, and tint in neutral tones. Each block should remain visually distinct from the blocks beside it.
Smooth gradients make color banding, abrupt tone changes, and panel tint easier to see, while color bars provide a quick comparison of primary and secondary colors.
Checkerboard and sharpness patterns help reveal scaling softness, uneven pixel rendering, moire, and whether fine lines remain distinct.
Browser test patterns can reveal visible display problems, but they do not calibrate color, measure hardware brightness, or replace professional measurement equipment.
