PatternScope TV

PatternScope TV turns your Apple TV into a complete display test-pattern suite — and actually explains what you're looking at. Whether you're setting up a brand-new TV, hunting for a dead pixel, or dialing in your picture settings, PatternScope TV gives you the same families of test patterns the pros use, plus guided workflows that walk you through each check step by step. NINE PATTERN CATEGORIES • Calibration — SMPTE bars, grayscale, PLUGE black level, white clip, gamma, sharpness and overscan • Geometry & convergence — crosshatch, circles, starburst and RGB convergence to check screen geometry and alignment • Uniformity — full-field gray, white, black and color to reveal clouding, banding and tint • Dead & stuck pixels — color scans and a pixel grid to find stuck subpixels • Motion — pans, the UFO test and response patterns for blur and judder • Mini-LED / FALD — local dimming, zone transitions, blooming and black uniformity • OLED — near-black detail, brightness windows and an image-retention check • HDR & brightness — HDR readiness, PQ ramp, highlight detail and clipping • Audio / video sync — flash-and-beep, adjustable offset and lip-sync aids PATTERNSCOPE PRO (optional one-time purchase) Turn a nearby iPhone or iPad into a measurement microphone using Apple's Continuity Camera & Microphone — no companion app. Measure relative speaker levels with trim suggestions, room frequency response, subwoofer integration, relative timing and polarity, and your system's A/V-sync offset. Save sessions and export reports over your local network. All processing happens on your Apple TV; nothing is recorded or uploaded. Everything in the free app stays free. GUIDED WORKFLOWS Eleven step-by-step walkthroughs, from a Quick TV Health Check to a full New-TV Inspection — each with plain-English notes on exactly what to look for. DESIGNED FOR THE LIVING ROOM Driven entirely by the Siri Remote, with clear on-screen explanations. An Apple TV 4K is recommended for 4K and HDR patterns. PRIVATE BY DESIGN No account, no sign-in, no network access, no analytics or tracking. Nothing ever leaves your Apple TV. A NOTE ON SAFETY PatternScope TV is a diagnostic tool, not a repair tool: it helps you find display problems but cannot repair burn-in, dead pixels, or other permanent panel defects. Some patterns display bright, sustained fields, and one optional Motion test (the Flicker Helper) deliberately flashes. The flashing test is capped at a low rate, starts paused, shows a photosensitivity warning, honors the system "Reduce Flashing" setting, and is excluded from the guided workflows. If you — or anyone who can see the screen — have photosensitive epilepsy or are sensitive to flashing light, do not use the deliberately flashing test.
