The MSI MPG 321CURXDE QD-OLED 31.5" gaming monitor features a 3840 x 2160 (4K UHD) QD-OLED panel that delivers vibrant colors and deep blacks. Designed for fast-paced gaming, it combines a high 240Hz refresh rate with an extremely low response time (0.03–0.05 ms GtG depending on source) and VESA certifications including ClearMR 13000 and DisplayHDR True Black 400. OLED Care 2.0 helps reduce the risk of OLED burn-in. Console support includes HDMI 2.1 ports with 48 Gbps bandwidth, 120Hz support, VRR and ALLM.
