Our take on the MSI MPG 321CURX QD-OLED Gaming Monitor
The MSI MPG 321CURX is a 32-inch curved 4K gaming monitor built on a third-generation QD-OLED panel. It pairs a 3840x2160 resolution with a 240Hz refresh rate and a 0.03ms GtG response time, which is the combination that sets it apart from most 4K rivals that top out at 144Hz or 160Hz. Color is factory-tuned to Delta E≤2 and it carries VESA DisplayHDR True Black 400, so HDR highlights and dark scenes hold up well. It suits competitive and single-player gamers who want 4K sharpness and OLED contrast on one screen, plus a built-in KVM for switching between a desktop and a laptop. The main trade-offs are the usual OLED ones: burn-in risk (mitigated by MSI OLED Care 2.0), full-screen brightness below a good Mini-LED, and a matte coating some buyers prefer glossy.

Questions and answers
- Is 240Hz at 4K worth it over a 144Hz 4K monitor?
- Yes if you play fast shooters or racing games and have a GPU that can push high frame rates at 4K. The jump from 144Hz to 240Hz is noticeable in motion, though the benefit is smaller in slower single-player games.
- Does it work well with a PS5 or Xbox Series X?
- It has two HDMI 2.1 ports, so consoles can run 4K at up to 120Hz with HDR. You won't get 240Hz from a console, but the panel handles console modes well.
- How does it compare with the older MPG 321URX?
- Both are 32-inch 4K QD-OLED monitors at 240Hz. The 321CURX adds a curved screen, while the 321URX is flat; pick based on whether you prefer curve immersion or a flat panel for desk work.
- Will the OLED panel burn in?
- Burn-in is possible on any OLED with static content, but MSI OLED Care 2.0 adds pixel-shift and panel-care routines to reduce the risk. Vary content and let the monitor run its care cycles.
- What's in the box?
- The monitor, stand, power cable and display cables for its HDMI and DisplayPort inputs. Check the specific listing for which cables are included.
- Can I mount it on an arm?
- Yes. It has a VESA mount and the stand is height-adjustable and tilts, so you can use a desk arm or wall mount instead.
