HARDWARE ARCHITECTURE

Panel Technology Breakdown

Professional IPS (In-Plane Switching)

Superior color accuracy and viewing angles. Used in reference monitors. Prone to minor 'IPS Glow' in dark environments.

Consumer IPS (Fast IPS / Nano IPS)

High refresh rates and good response times for gaming, but lower static contrast ratios compared to VA.

VA Panel (Vertical Alignment)

Excellent deep blacks and high contrast (3000:1+). Often used in curved displays. Can exhibit 'black smearing' in fast motion.

OLED (Organic LED) & QD-OLED

Self-lit pixels deliver true black, near-instant response times, and infinite contrast. Subject to Auto Brightness Limiting (ABL).
