The MSI MPG 321URX is a flat 32-inch, 4k gaming monitor with a 240Hz refresh rate. As a part of MSI's Performance Gaming (MPG) lineup, it sits alongside other QD-OLED monitors, like the 27-inch 1440p MSI MPG 271QRX QD-OLED. MSI also has a very similar monitor, the MAG 321UPX QD-OLED, which lacks some of the extra features of the 321URX, such as 90W of power delivery over USB-C. It competes with several other 32-inch OLED monitors, like the ASUS ROG Swift OLED PG32UCDM and the Samsung Odyssey OLED G8/G80SD S32DG80. Unlike some monitors, it uses a heatsink instead of a fan to dissipate heat. It also has several non-gaming features, such as a KVM switch, making it easy to multitask with different computers. MSI also offers a three-year warranty on the monitor, which includes burn-in coverage.
Our Verdict
The MSI MPG 321URX is remarkable for PC gaming. It has a high 240Hz refresh rate with very low input lag for a responsive feel, and motion also looks extremely crisp thanks to its near-instantaneous response time. Its near-infinite contrast ratio in dark rooms and perfect black uniformity are ideal for dark room gaming, as blacks look deep and inky. It also gets bright enough for highlights to pop, and colors look rich and vivid.

The MSI MPG 321URX is good for office work but has some limitations. Its large screen makes it easy to multitask, and its high 4k resolution helps produce excellent text clarity without too much noticeable fringing around text. It also has wide viewing angles that make it easy to share your screen with others. However, while it works well with a few lights around, it doesn't get bright enough to fight strong glare. Additionally, it has the risk of permanent burn-in with constant exposure to the same static elements over time, which could be a problem if you're only using it for office work.
- Bright enough to fight glare in most rooms.
- 90W USB-C charging and KVM switch.
- Sharp text and image clarity.
- Risk of burn-in.
The MSI MPG 321URX is incredible for photo and video editing. It displays a wide range of vivid colors and is very accurate before calibration. Its large 4k screen provides a detailed workspace for editing content, and you can easily have multiple windows open at the same time. It's also great for editing content in HDR, as small highlights get bright enough to pop, and it displays a wide range of colors. However, if there's a lot of light shining on the screen, it appears slightly purple, so you'll have more difficulty editing very dark content accurately if this occurs. Also, there is the risk of permanent burn-in with constant exposure to the same static elements over time, like if you always have your editing programs on the screen.

Differences Between Sizes And Variants
We tested the 32-inch MSI MPG 321URX, which is the only size available. It's one of several monitors in MSI's lineup that features a QD-OLED panel, including the very similar MSI MAG 321UPX QD-OLED. However, that monitor is different as it only delivers 15W of power over USB-C. The results are only valid for this model and the MPG 321URXW, which has a white body instead.
| Model | Size | Resolution | USB-C Power Delivery | KVM Switch | Refresh Rate | Color |
|---|---|---|---|---|---|---|
| MPG 321URX QD-OLED | 32" | 4k | 90W | Yes | 240Hz | Black |
| MPG 321URXW QD-OLED | 32" | 4k | 90W | Yes | 240Hz | White |
| MAG 321UPX QD-OLED | 32" | 4k | 15W | No | 240Hz | Black |
Our unit was manufactured in April 2024; you can see the label. We tested it with firmware FW.011.
Popular Monitor Comparisons
The MSI MPG 321URX is a superb gaming monitor for PC and console gamers. Its 4k resolution ensures a detailed image, and its 240Hz display provides a crisp and responsive feel. It displays deep blacks next to bright highlights in a dark room, and small highlights pop. Like several other 32-inch 240Hz OLEDs, such as the ASUS ROG Swift OLED PG32UCDM and the Gigabyte AORUS FO32U2P, it has several features to help enhance productivity, such as a USB-C port with 90W of power delivery and a KVM switch. It has considerably less VRR flicker than most OLEDs, so it's a great option if you're sensitive to VRR flicker. However, it doesn't have Dolby Vision support, so if that's important, you may want to consider another similar monitor like the Dell Alienware AW3225QF.
Also, make sure to check out our recommendations for the best OLED monitors, the best gaming monitors, and the best HDR gaming monitors.
The ASUS ROG Swift OLED PG32UCDM and the MSI MPG 321URX QD-OLED are both 32-inch 4k @ 240Hz QD-OLED monitors. The ASUS is the better option for most people, as it has Dolby Vision support, and content available in that format will look better. Additionally, the ASUS has a black frame insertion feature to reduce persistence blur and three USB-A ports with much faster throughput. However, the MSI is a better option if you find VRR flicker distracting, as it has less VRR flicker.
The Dell Alienware AW3225QF and the MSI MPG 321URX QD-OLED are both 32-inch 4k @ 240Hz QD-OLED monitors. The Dell is the better choice if video quality is important to you, as it has Dolby Vision support, and content available in that format will look better. It also has a curved screen, which you may or may not prefer, depending on your preferences. However, the MSI is better for productivity, as it has a KVM switch and delivers up to 90W of power over USB-C.
The Samsung Odyssey OLED G80SD S32DG80 and the MSI MPG 321URX QD-OLED are 32-inch 4k @ 240Hz QD-OLED monitors. The MSI is the better option if USB connectivity is important to you, as it delivers 90W of power over USB-C and has a KVM switch. However, the Samsung monitor is a better choice if you plan to use the monitor as a TV, as it has a remote and integrated apps like Netflix. You may also prefer the Samsung if you're in a room with a lot of ambient light, as it has a matte screen and reduces glare really well.
The MSI MPG 321URX QD-OLED and the LG 32GS95UE-B are both 4k OLEDs. The MSI is a better option if you play a lot of immersive games, as it has more vivid colors. However, the LG is a better option if you're a competitive gamer, as it has a 1080p @ 480Hz Dual-Mode with extremely low input lag.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
