When MOBIUZ Game Art Meets QD-OLED. A New Era BeginsPowered by 4th Gen QD-OLED with a 5-layer tandem structure, this display delivers insane contrast and lifelike visuals.

The flagship setup is completed by three refinements: Brightness Flow for stability, Reinforced Surface for deep blacks, and 3H hardness coating for extreme durability.
Visual Stability: Brightness FlowTraditional OLE
Ds use ABL, causing flicker. EX321UZ solves this with Brightness Flow. It analyzes scenes to adjust pixel brightness in real time, stabilizing luminance. This keeps scenes vivid yet deep, reducing eye fatigue.
Deep Blacks: Reinforced SurfaceEX321UZ's Reinforced Surface boosts visual quality. It enhances perceived black depth by 40%, keeping dark areas rich and defined by reducing reflections and ambient light interference.
Maximum Durability: 3H Hardness CoatingThe 3H reinforced coating boosts surface hardness, delivering 2.5X greater scratch resistance than previous OLED panels. It protects your display from daily wear, ensuring the premium durability of your flagship monitor lasts.
Advanced Thermal Design: Dual-ProtectionA graphene film layer forms the foundation of BenQ's thermal approach, dispersing heat and preventing pixel aging. Building on this, the flagship EX series further adds an aluminum-plated mechanism to maximize heat dissipation and panel stability.
Intelligent OLED Protection Suite: Proactive ProtectionPixel Refresh balances luminance, while Idle Dimmer and Logo Dimming reduce static stress. Pixel Shift subtly moves images to prevent uneven wear, ensuring long-term reliability.
