Home Theater Calibration

Get mathematically pure test signals for your high-end display. Unlock 87 pixel-perfect patterns plus phase, crossover, and room-tuning diagnostics.

Stop guessing at your settings and unlock the absolute true potential of your high-end display and surround sound system. This professional-grade diagnostic suite is engineered for total signal integrity. Say goodbye to heavily compressed video that alters color spaces, generates fake metadata, and ruins pixel accuracy. By utilizing custom graphics shaders and raw audio engine programming, this app delivers mathematically pure, uncompressed, 1:1 test signals directly to your gear.

Whether you are mapping an HDR tone curve, stress-testing a local dimming array, or phase-aligning a discrete Atmos receiver, you now have 87 reference patterns and the exact tools professionals rely on, right from your couch.

PIXEL-PERFECT VIDEO CALIBRATION True 1:1 Mapping: Custom graphics shaders bypass system scaling to deliver absolute 1-pixel checkerboards, grid lines, and crosshairs. Instantly identify artificial edge enhancement or sharpness artifacts. Resolution & Banding: Multiburst sweeps expose soft scaling and over-sharpening, while 6-bit, 8-bit, and 10-bit gradient bands reveal how cleanly your panel handles shadow detail. Overscan & Framing: Verify your display is mapping exactly to the physical edges of the screen, and frame projectors with aspect-ratio markers and a dedicated alignment cross. SDR & HDR Clipping: Dial in your absolute black levels and peak white clipping points with precision reference steps. ADVANCED HDR & CHROMA PACK Wide Color Gamut Test: Does your display hit the target, or is it faking it? Our Gamut Clipping pattern draws extreme coordinates against a pure 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 display color processing. Local Dimming Stress Tests: Push your display’s algorithms to the breaking point. Spawn multiple high-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! Room & Speaker Tuning: Octave-band noise, a room-mode finder, per-channel reference level, delay pulses, tone bursts, and phantom-imaging checks let you tune the room itself, not just the gear. Subwoofer Integration: Sweep a pure 20Hz to 200Hz sine wave to hear where your mains hand off to your subwoofer, then blend level and phase right at the crossover for the fullest bass at your seat. Uncompressed Output: All signals are generated mathematically on the device via the native audio engine. No compressed files, no 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. Favorites & Sequences: Bookmark the patterns you use most often, then chain them into custom auto-advancing calibration sequences. Living Room UI: Beautiful, legible, high-contrast typography and controls designed specifically for viewing on massive screens from across the room.
