Evaluate Full-Array Local Dimming (FALD) zone response, blooming light bleed, and HDR subtitle halo artifacts.
Mini-LED displays utilize localized Full-Array Local Dimming (FALD) backlight zones (typically 512 to 5,000+ zones). When a high-luminance white element (like movie subtitles or star fields) moves across a dark pitch-black background, zone dimming algorithms must balance contrast against Blooming Light Bleed.
Clean your monitor surface, disable ambient light sensors, and set your display to native resolution and refresh rate.
Enter full-screen mode (F11) and use the diagnostic suite controls to progress through the test patterns.
Observe anomalies from different viewing angles in a dark room. Reference our testing guides to interpret your results.
Superior color accuracy and viewing angles. Used in reference monitors. Prone to minor 'IPS Glow' in dark environments.
High refresh rates and good response times for gaming, but lower static contrast ratios compared to VA.
Excellent deep blacks and high contrast (3000:1+). Often used in curved displays. Can exhibit 'black smearing' in fast motion.
Self-lit pixels deliver true black, near-instant response times, and infinite contrast. Subject to Auto Brightness Limiting (ABL).
Our testing methodology aligns with VESA, SMPTE, and ISO standards for display metrology. This diagnostic tool utilizes raw web APIs (Canvas, WebGL, CSS Color Level 4) to ensure bit-perfect rendering, bypassing OS-level compression and scaling where possible.
