MSI MPG 321URXW QD-OLED 31.5" 4K Gaming Monitor 4FA 240Hz, 0.03ms, 99% DCI-P3, HDR True Black 400

Immersive visuals meet cutting-edge technology

The MSI MPG 321URXW combines an OLED self-emitting panel with Quantum Dot color to deliver a 31.5-inch 4K UHD experience at 3840 x 2160. With 1.07 billion colors (10-bit) and 99% DCI-P3 coverage, you get rich, nuanced color and silky gradients. DisplayHDR True Black 400 certification yields deep blacks and bright highlights, reaching up to 1000 nits in peak brightness while preserving native contrast for scenes that feel genuinely cinematic.

The panel is designed for accuracy and depth, featuring Delta E a02 color fidelity and crisp edge definition. This combination aims to convey a sense of realism across games, films, and creative work, without assuming a guaranteed outcome. The result can be particularly striking in dark tones and HDR content, where true blacks and vibrant colors matter most.

Ultra-responsive motion and pristine clarity

Motion is where this monitor shines: a blistering 0.03 ms GtG response time paired with up to 240 Hz refresh creates extremely smooth transitions and reduced motion blur. A graphene-based passive heatsink helps maintain performance in longer sessions without fan noise, supporting reliable color and contrast during fast-paced gameplay.

Smart features and flexible workflows

MSI GI software brings OLED Care 2.0 to help manage burn-in risk, while AI-assisted tools like Smart Crosshair assist on-screen aiming in supported titles. Console modes, Game Assistance, and KVM with PiP/PbP enable convenient multi-device work or play from a single screen. RGB lighting adds a subtle, customizable ambiance without distracting from the action.

Ergonomics and connectivity for modern setups

The monitor includes a 4-way adjustable stand (pivot, tilt, swivel, height) and is VESA mountable for wall or arm setups. Port selection covers DisplayPort 1.4a, HDMI 2.1 (CEC), and USB Type-C with 90 W Power Delivery, complemented by a USB hub for peripherals. This combination is designed to fit diverse PC, laptop, and console configurations.
