Home Theater Calibration

Apple TV / Utilitaires

Stop guessing at your settings and unlock the absolute true potential of your high-end display and surround sound system.

The Home Theater Calibration Toolbox is a professional-grade diagnostic suite engineered exclusively for the Apple TV 4K. Say goodbye to heavily compressed streaming videos that alter color spaces, fake HDR metadata, and ruin pixel accuracy. By utilizing custom Apple Metal shaders and raw audio engine programming, this app bypasses OS restrictions to deliver mathematically pure, uncompressed, 1:1 test signals directly to your gear.

Whether you are mapping an OLED’s HDR tone curve, stress-testing a Mini-LED’s local dimming zones, or phase-aligning a discrete Dolby Atmos receiver, you now have the exact tools professionals rely on—right from your couch.

PIXEL-PERFECT VIDEO CALIBRATION
True 1:1 Mapping: Custom Metal shaders bypass tvOS scaling to deliver absolute 1-pixel checkerboards, grid lines, and crosshairs. Instantly identify artificial edge enhancement or sharpness artifacts.

Overscan & Framing: Verify your display is mapping exactly to the physical edges of the screen with absolute UV-edge boundaries and safe-area borders.

SDR & HDR Clipping: Dial in your absolute black levels and peak white clipping points with precision reference steps.

ADVANCED HDR & CHROMA PACK
BT.2020 Wide Color Gamut Test: Does your display actually hit BT.2020, or is it faking it? Our Gamut Clipping pattern draws extreme BT.2020 coordinates against a pure DCI-P3 background to expose hardware color limits.

10-Bit Color Gradients: Ultra-smooth PQ-encoded RGB sweeps reveal 8-bit banding and expose aggressive, low-quality TV color processing.

Local Dimming Stress Tests: Push your Mini-LED or FALD (Full Array Local Dimming) algorithms to the breaking point. Spawn multiple 10,000-nit PQ windows on pure black backgrounds and adjust object counts and motion speeds to expose backlight blooming and processing lag.

REFERENCE AUDIO DIAGNOSTICS
Phase & Polarity Test: Are your speakers fighting each other? Generate pure dual-mono tones and instantly invert the right channel's phase. If the inverted signal sounds fuller, your speaker wires are physically reversed!

Subwoofer Crossover Blend: A pure, sweeping 20Hz to 200Hz sine wave lets you physically hear where your main speakers hand off to your subwoofer. Easily identify phase cancellation and volume dips right at your AVR's crossover frequency.

Uncompressed Output: All signals are generated mathematically on the device via the native audio engine—no compressed MP3s or lossy streaming artifacts.

BUILT FOR THE LIVING ROOM
Guided Quick-Check Mode: Don't know where to start? Launch our curated, auto-advancing wizard. It walks you through the most critical video and audio patterns step-by-step, saving your progress along the way.

Custom Favorites: Bookmark the patterns you use most often for instant access at the top of your catalog.

10-Foot UI: Beautiful, legible, high-contrast typography and controls designed specifically for viewing on massive screens from across the room.
