Dynamic Range & Gamma Calibration

Contrast 32-Step Matrix Test

Evaluate shadow detail, highlight separation, and gamma 2.2 tracking with 32 discrete luminance blocks from 0% pure black to 100% pure white.

01

Shadow Detail (0% - 10%)

Step 1 (#080808) and Step 2 (#101010) must be distinguishable from pure black (#000000). If they blend into black, your monitor is crushing shadows.

16

Midtone Gamma (45% - 55%)

Midtone blocks around step 16 verify accurate standard Gamma 2.2 tracking for accurate color grading and photo editing.

32

Highlight Clipping (90% - 100%)

Step 31 (#F7F7F7) must remain visible against Step 32 (#FFFFFF). If they are indistinguishable, your display's contrast setting is too high.

How to Calibrate Your Monitor Using the Matrix

  1. Step 1 (Black Level): Adjust your monitor's "Black Level" or "Brightness" OSD setting until Step 1 and Step 2 are barely visible against the background.
  2. Step 2 (White Level / Contrast): Adjust your monitor's "Contrast" OSD setting until Step 31 is clearly distinct from the pure white border of Step 32.
  3. Step 3 (Gamma): Select Gamma 2.2 or sRGB in your monitor's picture profile menu.
Automated Diagnostic Engines

Pre-Built Screen Test Modules

Run dedicated hardware-level automated test patterns to diagnose panel defects, calibration anomalies, response times, and subpixel clarity.

Defect Scan

Dead & Stuck Pixel Scanner

Automatically cycles through high-contrast primary RGB and CMY solid colors to easily spot permanently dead (black) or stuck (single color) subpixels.

Interval:
Uniformity

Backlight Bleed & IPS Glow

Presents a 100% pure black field with subtle corner and edge quadrant markers to inspect light leakage on IPS, VA, and edge-lit LED displays.

OLED / Dark Room
Pixel Exerciser

OLED Burn-in & Ghosting

High-frequency rapid color cycling and noise dithering to unstick stubborn pixels, test for image retention, and exercise OLED phosphors.

60fps Strobe
8-bit / 10-bit

Color Uniformity & Banding

Renders ultra-smooth horizontal/vertical color ramps and grayscale steps to diagnose color stepping, banding, and dirty screen effect (DSE).

Smooth Ramps
Calibration

Contrast & Gamma Matrix

32-step shadow detail (0%–15% IRE) and highlight blocks (85%–100% IRE) to detect crushed shadow blacks and clipped highlight whites.

Motion Clarity

Motion Blur & UFO Refresh Rate

High-speed animated UFO objects moving at pixel-synchronized velocities with real-time FPS/Hz detection to test display ghosting and MPRT.
