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.
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.
Midtone Gamma (45% - 55%)
Midtone blocks around step 16 verify accurate standard Gamma 2.2 tracking for accurate color grading and photo editing.
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
- 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.
- 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.
- Step 3 (Gamma): Select Gamma 2.2 or sRGB in your monitor's picture profile menu.
Pre-Built Screen Test Modules
Run dedicated hardware-level automated test patterns to diagnose panel defects, calibration anomalies, response times, and subpixel clarity.
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.
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 Burn-in & Ghosting
High-frequency rapid color cycling and noise dithering to unstick stubborn pixels, test for image retention, and exercise OLED phosphors.
Color Uniformity & Banding
Renders ultra-smooth horizontal/vertical color ramps and grayscale steps to diagnose color stepping, banding, and dirty screen effect (DSE).
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 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.
Text & Subpixel Clarity
High-density 1-pixel micro-grids and font rendering tests across varied point sizes to check ClearType antialiasing and RGB/BGR subpixel layouts.
Ambient Ring Light & Glow
Transforms your monitor into a soft studio ring light or warm ambient glow for Zoom video calls, streaming, and soft night desk lighting.
Solid Color Palette & Custom Shade Generator
Select from standardized screen calibration shades or generate custom RGB/Kelvin values for panel analysis, photography backdrops, and ambient lighting.
