Product description
This 31.5 inch QD-OLED monitor from MSI brings 4K resolution and gaming-focused speed to immersive PC and console setups, combining deep blacks with a high refresh rate for fluid visuals and accurate colour. It suits competitive gamers and creative users who need both responsiveness and reliable colour rendition according to the manufacturer.
Key Points
The panel merges Quantum Dot colour conversion with self-emitting OLED pixels to deliver strong contrast and vivid hues while maintaining rapid pixel response for fast-paced scenes. With a 240 Hz refresh rate and an ultra-fast 0.03 ms GtG response, motion looks very smooth and ghosting is minimised, which is useful in shooters and racing titles.

Advantages
The combination of Quantum Dot processing and an OLED emissive matrix results in exceptionally deep black levels and strong native contrast, which improves perceived detail in dark scenes. Colour fidelity is a highlight thanks to the wide DCI-P3 coverage and a Delta E of 2 or less according to the specifications, making the screen suitable for colour-critical tasks as well as gaming. Connectivity options are comprehensive, with DisplayPort 1.4a and HDMI 2.1 supporting UHD at high frame rates, plus USB Type-C that can deliver up to 90 W to compatible laptops, simplifying single-cable docking.
Usage Recommendations
For desktop use, make sure the monitor is placed where its HDR peak brightness and deep blacks can be appreciated in mixed lighting, and consider enabling the MSI OLED Care 2.0 features to limit static-image retention over prolonged sessions. When using consoles, select the matching HDMI 2.1 settings on the console to take advantage of 4K at high frame rates. The KVM and PiP/PbP functions can help those who need to switch between multiple systems quickly, and the fanless graphene heatsink design reduces audible noise while helping maintain panel longevity. Note that while HDR peak brightness is listed up to 1000 nits by the manufacturer, sustained brightness for HDR scenes may vary depending on content and settings.
