8 Test Modules
Automated hardware diagnostic engines for dead pixels, IPS bleed, OLED burn-in, and motion blur.
Color Palette Studio
Pure solid RGB swatches, 16-step grayscale shadows, and custom Kelvin color temperature slider.
4K Image Exporter
Download uncompressed solid test patterns and wallpapers in 4K UHD, 1440p, 1080p, and mobile formats.
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.
Primary & Secondary Calibration
Grayscale & Shadow Steps
Color Temperature & Lighting Presets
Custom Shade & Kelvin Studio
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.
Live Display & Monitor Diagnostics
Accurate hardware data detected directly from your connected display, GPU pipeline, and browser window.
