TV Calibration multi HDR & Modern Screen Calibration

The display calibration suite built for the modern HDR era. TV Calibration embeds lightweight hardware trigger streams that reliably engage your television's real HDR10, HDR10+, Dolby Vision, and HLG HDMI processing pipelines—overlaying pixel-perfect contrast, black-level, HCFR colorimeter windows, and alignment patterns with zero latency and full D-Pad remote control.

Engineered for True Display Precision

Solving the fundamental flaw of Android TV calibration apps: triggering actual television hardware HDR modes instead of clipping in SDR.

The Breakthrough: Real Hardware HDR Mode Triggering

Standard Android TV calibration tools render test patterns inside a regular 8-bit SDR surface. This means your TV remains locked in SDR picture mode, making it impossible to calibrate HDR tone-mapping, peak specular luminance, or wide color gamuts:

  • Embedded HDR Trigger Streams: TV Calibration packages native, lightweight HDR video assets (hdr10, hdr10plus, dolby, hlg) played in a hardware SurfaceView.
  • Forces Native Display Signal Chains: When you toggle a mode, the television immediately detects the HDMI signal flags and switches its physical panel backlight, EOTF gamma curve, and picture profile to actual HDR10 or Dolby Vision.
  • Transparent Test Pattern Overlay: A precision canvas renders directly over the HDR surface, allowing you to evaluate clipping, color primaries, and luminance under real HDR panel conditions.

Feature Spotlight: Peak Contrast & Black Levels

Eliminate Highlight Clipping & Black Crush

Improper contrast and brightness settings destroy image fidelity by blowing out specular highlights or swallowing fine shadow details in dark scenes:

  • Contrast Clipping Bars: High-resolution stepped bars from 90% up to reference 100% white allow you to set contrast so all highlight steps remain clearly distinguishable without blooming.
  • Brightness (Shadow Detail) Bars: Ultra-fine near-black bars (0% reference black up to 5% video levels) ensure true blacks remain pitch black while preserving subtle creases in dark clothing and night textures.
  • Color Gain Balance: Primary and secondary color ramps (Red, Green, Blue, Cyan, Magenta, Yellow) to calibrate individual sub-pixel drive gains and eliminate tinting.

HCFR & Optical Probe Window Generation

Ready for advanced calibration with spectrophotometers and colorimeters (e.g. X-Rite i1Display Pro, Spyder, Klein). TV Calibration generates standardized test windows designed to avoid OLED Automatic Brightness Limiter (ABL) throttling:

  • Selectable Window Sizes: 10% Window (standard for OLED/Mini-LED probe profiling), 18% Window (for cinema gamma), and Fullscreen (for uniformity testing).
  • Color Space Standards: Instant switching between Rec. 709 (sRGB / HDTV), Display P3 (wide gamut), and Rec. 2020 (ultra-wide HDR mastering gamut).
  • 10-Point Grayscale Ramp: Full 10% increments from 0% Black to 100% Peak White, plus 100% saturation targets for all 6 primary and secondary colors.

Feature Spotlight: Geometry & Overscan

Geometry, 1:1 Pixel Mapping & Overscan Check

Modern TVs frequently crop screen edges by 2.5% to 5% by default ("overscan"), destroying bit-perfect 4K clarity. TV Calibration gives you the tools to ensure 100% unscaled pixel mapping:

  • 1:1 Pixel Grid: Single-pixel alternating line patterns immediately reveal unwanted digital sharpening or non-native scaling.
  • Overscan Markers: 0%, 2.5%, and 5% perimeter borders show exactly how much image area is being cropped by your television's aspect ratio settings.
  • Concentric Circular Geometry: Verifies that width and height aspect ratios are locked without distortion.

Comprehensive Test Pattern Library

All patterns render dynamically with zero scaling artifacts, matching your screen's exact native resolution.

Contrast & Highlight Clipping

Fine-tune peak white output without blowing out clouds, reflections, and explosions.

  • Stepped White Bars: Reference 100% white with 90%–99% step comparisons.
  • Anti-Blooming Assessment: Evaluate FALD (Full Array Local Dimming) zone halos.
  • EOTF Tone-Mapping: Observe hard clipping thresholds in HDR10 modes.

Brightness & Shadow Detail

Ensure pitch blacks while revealing every subtle detail in dark cinema scenes.

  • Near-Black Bars: 0%, 1%, 2%, 3%, 4%, and 5% luminance indicators.
  • Zero Black Crush: Dial in black levels until 1%–2% bars are barely visible in a dark room.
  • Backlight Glow Check: Detect elevated panel black levels and clouding.

Color Gain & Saturation

Balance individual color drives to eliminate unnatural skin tones and color casts.

  • 6-Color Test Bars: Red, Green, Blue, Cyan, Magenta, Yellow.
  • Sub-Pixel Gain Calibration: Adjust 2-point or multi-point white balance.
  • Clipping by Color: Detect clipping on saturated red or blue channels.

HCFR Colorimeter Windows

Engineered for professional color calibration software and optical probes.

  • 10% Window Mode: Prevents OLED thermal drop and ABL dimming.
  • Full Grayscale Ladder: 10% increments from 0% Black to 100% White.
  • Gamut Selection: Rec.709, Display P3, and Rec.2020 color target profiles.

Alignment, Sharpness & 1:1 Pixel

Disable artificial TV post-processing and ensure perfect 1:1 pixel rendering.

  • 1:1 Pixel Check: Single-pixel lines expose artificial haloing and sharpness artifacts.
  • Overscan Detection: 0%, 2.5%, 5% markers to turn off "16:9 zoom" / overscan.
  • Geometry Verification: Perfect circular overlays check for aspect distortion.

Burn-In & Panel Uniformity

Examine panel cleanliness across Fullscreen 5%–100% fields.

  • Fullscreen 5% Gray: The definitive test for OLED near-black vertical banding.
  • Dirty Screen Effect (DSE): Fullscreen fields reveal backlight uniformity flaws.
  • Dead & Stuck Pixels: Fast cycling through pure Red, Green, Blue, and White.
