MSI MAG 321UPX QD-OLED - 31.5" 4K UHD 240Hz Gaming Monitor

Third-Gen QD-OLED Meets Blistering 240Hz Speed

The MSI MAG 321UPX QD-OLED pairs a 31.5-inch 4K UHD (3840 x 2160) third-generation QD-OLED panel with a 240Hz refresh rate and a 0.03ms (GTG) response time, giving fast-paced games and detailed creative work exceptional sharpness with virtually no motion blur. VESA DisplayHDR True Black 400 certification, ClearMR 13000, and QD Premium Color combine to deliver deep blacks, strong highlights, and precise color reproduction across 99% DCI-P3, 97.5% Adobe RGB, and 138.2% sRGB with Delta E <= 2 accuracy.

MSI OLED Care 2.0 protects long-term panel health through pixel shift, panel protect, and static screen detection, backed by a graphene film, custom heatsink, and fan-less cooling for quiet, efficient operation. A smart 24-hour refresh cycle keeps maintenance unobtrusive by running during standby or shutdown rather than interrupting active use.

Connectivity is built for both PC and console gaming, with dual HDMI 2.1 ports supporting 4K at up to 240Hz alongside VRR and ALLM, plus a USB Type-C port offering DisplayPort Alt Mode and 15W Power Delivery charging. Adaptive-Sync, AI Vision, Smart Crosshair, and a fully adjustable ergonomic stand round out the package, which is backed by a 3-year warranty covering OLED burn-in.
