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

The MSI MPG 321URXW QD-OLED 31.5" monitor delivers a 3840 x 2160 (4K UHD) QD-OLED panel with a native 16:9 aspect ratio and wide 178° viewing angles. It combines a 240 Hz refresh rate, a very fast 0.03 ms (GtG) response time and VESA-certified ClearMR 13000 and DisplayHDR True Black 400 to provide vivid images with reduced motion blur. Features include OLED Care 2.0 to lower burn-in risk, a built-in USB hub with a downstream USB Type-C port, VESA mount compatibility and ergonomic height adjustment. The monitor comes in a white finish and does not include built-in speakers.

Advantages

The QD-OLED panel ensures excellent color accuracy and high contrast (typical 150000:1) while the 240 Hz refresh rate and 0.03 ms response time minimise ghosting and motion blur for fast-paced content. VESA certifications for ClearMR and DisplayHDR True Black 400 confirm strong motion handling and improved HDR black levels. OLED Care 2.0 helps mitigate the risk of image retention, and connectivity including HDMI 2.1 (48 Gbps), VRR and ALLM supports modern consoles and high-bandwidth PC graphics.

Suitable for

• Competitive and fast-paced gaming on PC and consoles
• Content creation and color-critical work requiring wide color accuracy
• Watching HDR video with deep blacks and vivid colors
• Ergonomic desktop setups that require VESA mounting or height adjustment

Adjust the height for ergonomic viewing and select display settings on your device to match 3840 x 2160 resolution and the desired refresh rate. Enable VRR and ALLM on both the monitor and source device when available for optimal console gameplay. Use the on-screen display to fine-tune color, brightness and HDR settings.

Recommendations

To reduce the likelihood of OLED burn-in, enable the monitor's OLED Care 2.0 features, avoid leaving static high-contrast images on screen for long periods, vary content, and use automatic dimming or screen-saver options when idle.
