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

The MSI MPG 321URXW QD-OLED is a 31.5" 4K UHD gaming monitor with a QD‑OLED panel that delivers vivid colors and deep blacks. It features a 3840 x 2160 resolution, a 240 Hz refresh rate and an extremely fast 0.03 ms (GtG) response time. The monitor includes HDMI 2.1 ports with 48 Gbps bandwidth supporting 120 Hz, VRR and ALLM for console compatibility, ClearMR 13000 VESA certification and DisplayHDR True Black 400. Built‑in USB hub, VESA mount support and height adjustment enable ergonomic setup for both gaming and professional use.

Advantages

The QD‑OLED panel provides high color saturation and deep blacks, while the 240 Hz refresh rate and 0.03 ms response time reduce motion blur and input lag. VESA ClearMR 13000 and DisplayHDR True Black 400 certification ensure accurate motion rendering and improved HDR contrast. OLED Care 2.0 helps reduce the risk of image retention. Multiple input options including HDMI 2.1, DisplayPort and a downstream USB‑C port allow flexible connectivity for PCs and consoles.
