Uniform fills, black/white ladders, gamma/ghosting/PWM labs, sharpness gratings, calculators (PPI/aspect/size/viewing distance), burn-in cycling, FPS and resolution diagnostics—all locally.
Screen 测试器Solid colors, dot grid, 和 fullscreen fills 用于 dead-pixel 和 uniformity checks.使用 →Refresh Rate ProbeEstimate animation frame cadence versus display refresh timing in-browser.使用 →Monitor 颜色 测试Swatches plus grayscale ladders 到 judge tint 和 near-black clipping.使用 →Backlight Bleed 测试Near-black fullscreen ramps 到 visualize edge glow on IPS 和 edge-lit LCDs.使用 →Touch Screen 测试Draw tap markers inside the arena 到 sanity-check mapping across the panel.使用 →Touch Sensitivity 测试Measure live touch force 和 detect graded pressure on touchscreens 和 styluses.使用 →Multi-Touch 测试Track simultaneous touch points 到 check multi-touch 和 palm rejection.使用 →Touch Response 测试Tap when the panel turns green 到 gauge touch response 和 input latency.使用 →PWM Flicker LabSimulated fullscreen brightness toggling across adjustable duty 和 frequency.使用 →Monitor Gamma RampStriped ramps 和 stepped grays highlight nonlinear gamma 和 sharpening halos.使用 →Monitor Ghosting 测试Watch the moving box. If you see a trailing blur 或 color smear behind it, your monitor has ghosting (slow pixel response). Increase speed 到 expose ghosting more clearly.使用 →Black Level 测试Free online black level test. 检查 whether your monitor crushes shadow detail 和 32 near-black patches. 检测 incorrect black-level mapping 和 gamma issues.使用 →White Level 测试Free online white level test. 检查 whether your monitor clips highlights 和 32 near-white patches. 检测 crushed whites 和 incorrect contrast settings.使用 →Brightness 测试Free online monitor brightness test. Eleven grayscale steps 从 black 到 white reveal brightness, contrast, 和 gamma issues.使用 →Contrast 测试Checkerboard beside 50% gray—squint 到 see if averaged checker matches solid mid gray 用于 contrast sanity.使用 →PPI 计算器Pixels per inch, dot pitch, megapixels, 和 aspect ratio 从 resolution plus diagonal.使用 →Aspect Ratio 计算器Simplify pixel dimensions 到 ratios (用于 example 3840×2160 到 16:9).使用 →Screen Size 计算器转换 diagonal 和 aspect ratio 为 physical width 和 height in inches 和 centimeters.使用 →Viewing Distance 计算器Rule-of-thumb seating distance 从 screen diagonal plus optional multiplier presets.使用 →FPS 测试Measured animation FPS 从 requestAnimationFrame timing 用于 qualitative render cadence.使用 →Screen Resolution 测试Browser-reported viewport, screen geometry, pixel ratio, 和 color depth diagnostics.使用 →OLED Burn-In 测试Cycle solid colors plus checker overlays fullscreen 到 spotlight uneven wear 或 risky static UI.使用 →颜色 Range 测试Near-black / near-white ladders 和 ramps 到 sniff limited HDMI (16–235) vs full RGB.使用 →颜色 Gamut 检查器Side-by-side sRGB, Display P3, 和 Rec. 2020 patches 到 judge wide-gamut rendering on your monitor.使用 →Screen Uniformity 测试Fullscreen reference fills across gray/black/white 和 primaries 到 inspect clouding 和 tint.使用 →Frame Skipping 测试Sample animation-frame spacing 和 highlight intervals much longer than the median streak.使用 →Monitor Sharpness 测试Lagom-inspired 1px stripes, grille patterns, 和 text blocks 到 gauge scaling 和 sharpening.使用 →
