MSI MPG 321URX QD-OLED computer monitor 80 cm (31.5 inch) 3840 x 2160 pixels 4K Ultra HD Black

The MSI MPG 321URX QD-OLED is a 31.5" 4K (3840 x 2160) gaming monitor that uses a next-generation QD-OLED panel to deliver vivid colors, deep blacks and high detail. It features a 240 Hz refresh rate, extremely fast 0.03 ms (GtG) response time, DisplayHDR True Black 400 and VESA ClearMR 13000 certification to reduce motion blur. Built-in OLED Care 2.0 helps minimize the risk of OLED burn-in. Console-ready connectivity includes HDMI 2.1 ports with 48 Gbps bandwidth, 120 Hz support, VRR and ALLM.

Advantages

The QD-OLED panel combines a blue self-emitting layer with a Quantum Dot conversion layer for improved color reproduction and deeper blacks. High refresh rate and ultra-fast response reduce motion blur and ghosting for smoother gameplay. OLED Care 2.0 provides pixel shift, panel protection and static-screen detection to lower burn-in risk. The monitor also includes ergonomic features and a relocated 5-way joystick at the bottom center of the rear for easier on-screen control.
