Highlights

• 26 pixel-perfect test patterns drawn losslessly to a canvas mapped 1:1 to your device pixels: OLED true black, near-black banding, dead pixels, motion clarity, backlight bleed, sharpness, gamma (γ 1.8–2.6), black/white clipping, gradients, touch, and GPU stress.
• Test All: 24 tests, 10 seconds each, with pause, skip, and progress.
• Guided Wizard: nine quick checks, then a report you can print, save as PDF, or export as JSON, with advice for each issue.
• Unobtrusive controls: hidden until you move toward them; pin with H.
• Refresh-rate detection (60–540 Hz) and frame-time stats.
• Private: no install, analytics, cookies, or third-party requests.
• Accessible and responsive: keyboard shortcuts for everything, light/dark themes, touch and swipe support.

⚠️ Some stress tests flash rapidly. The studio shows a photosensitivity warning, and flashing tests stop automatically.
