MSI 321CUP QD-OLED Overview

Catch every detail while competing in fast-paced matches with the MAG 321CUP QD-OLED 31.5" 4K HDR 165 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 165 Hz refresh rate, 0.03 ms response time, and NVIDIA G-Sync compatibility 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 15W of power. 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 165 Hz refresh rate and 0.03 ms response time, the MAG 321CUP reduces motion blur for smooth experiences during fast-paced scenes.
NVIDIA G-Sync
Reduce screen tearing with NVIDIA G-Sync compatibility. G-Sync 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.
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.

MSI 321CUP QD-OLED Reviews

Perfect

Purchased a Oled tv and this monitor From B&H the only place I buy my higher end electronics from. This monitor is great no issues with setup image is crazy good and has tons of settings. Pretty much plug n play games run smooth and the 1700r is just right for a 32" monitor. I was worried about using a curved monitor but within in a couple hours I didn't even notice it.

Brilliant Colors - Great Upgrade

I Bought Two Of These And Use Them Side-by-side For A Full Wrap Around Experience. They Are Totally Immersive And The Color Is Fantastic. I'll Never Go Back To LED Displays Again!
