MSI 321CURX QD-OLED Overview

Catch every detail while competing in fast-paced matches with the MPG 321CURX QD-OLED 31.5" 4K HDR 240 Hz Curved Gaming Monitor from MSI. Featuring a 1700R curved design with thin bezels, this UHD 4K 3840 x 2160 OLED display envelopes your field of view for maximum immersion. Additionally, the 240 Hz refresh rate and 0.03 ms response time with adaptive-sync support minimizes motion blur for smooth visuals.

This OLED display also delivers rich visuals with VESA DisplayHDR True Black 400 certified high-dynamic range support providing realistically bright highlights and deep shadows. You can connect your compatible devices through the dual HDMI 2.1 ports and DisplayPort 1.4a input. Or use the USB-C port with a compatible laptop to transfer video, audio, and up to 98W of power. An integrated USB hub and KVM allows you to control up to two connected devices in picture-in-picture or picture-by-picture mode using a single mouse and keyboard. Plug a pair of headphones into the 3.5mm jack for listening privacy. MSI's 3-year OLED warranty covers burn-in.

Stunning Color
The 31.5" Quantum Dot OLED panel delivers rich, cinematic visuals with 1.07 billion colors that's factory calibrated for Delta E ≤2 accuracy, covering 99% of the DCI-P3 gamut. VESA DisplayHDR True Black 400 certified high-dynamic range enhances highlights and shadows with a 1.5 million:1 contrast ratio and 1000 nits peak brightness.
Responsive Performance
With a 240 Hz refresh rate and 0.03 ms response time, the MPG 321CURX reduces motion blur for smooth experiences during fast-paced scenes.
Adaptive-Sync
Reduce screen tearing with adaptive-sync support. This technology enables the monitor to dynamically adjust its refresh rate to the frame rate being output by the graphics card, thereby greatly reducing screen tearing, stuttering, and other artifacts.
OLED Care 2.0
MSI OLED Care includes Pixel Shift, Panel Protect, Static Screen Detection technologies along with a graphene film and custom heatsink to help prevent burn-in. Boundary detection adjusts the luminance between two images or an image and background while taskbar detection automatically scans the shape of your taskbar to reduce its luminance. This display is also designed to automatically detect prominently contrasting logos and automatically scans their shape and color to reduce luminance.
Game Assistance
Smart Crosshair places an aim dot at the center of the screen. Its color dynamically changes its color to stand out from the background colors. Optix Scope magnifies a screen area at the touch of a shortcut key, allowing you to snipe opponents. AI Vision technology reveals details in darkened environments while enhancing the brightness and color saturation.
Console Mode
Enjoy smooth visuals with your connected console system with a 120 Hz refresh rate. Variable Refresh Rate (VRR) support reduces screen tearing and stuttering while auto low-latency mode (ALLM) sets the ideal latency for near lag-free responsiveness. HDMI CEC support automatically wakes the screen and switches the input to connected computers along with PlayStation and Nintendo Switch consoles by activating their respective controllers.
Gaming Intelligence
Adjust your monitor's setting with ease using the free Gaming Intelligence desktop app.
Ergonomics
Adjust the height, tilt, and swivel to optimize your viewing. You can also use the 100 x 100mm VESA mounting pattern to place the display on a swivel arm or multi-monitor stand. With 178° horizontal and vertical viewing angles, you can see the screen clearly from almost any position. Anti-reflection and blue light reducing technologies help to reduce eyestrain during extended viewing.

The goat OLED Monitor!!

By Guzman
Rated 5 out of 5
Date: 2026-02-09

Simply the best monitor I've owned. I have had many monitors and, most recently, a couple of OLED TV's of different brands and this monitor has provided the best experiences I've ever had for the month that I had it. Visual fidelity has been 10/10!!

Great monitor

Very nice 4K monitor, super clear, even when reading text on screen. I came from a 34-inch ultrawide monitor, so this one was a little hard to get used to, but after two weeks, it has been a real pleasure. Coming from a 1st gen QD-OLED ultrawide, this monitor has very little VRR flicker in games. I was pleasantly surprised!
