The MSI MPG 341CQPX QD-OLED is a 34-inch 1440p ultrawide gaming monitor with a QD-OLED panel. It competes against other ultrawide OLED monitors like the LG 34GS95QE-B and the Gigabyte AORUS MO34WQC2. It has a 240Hz refresh rate, VRR support, and HDMI 2.1 bandwidth that lets it take full advantage of gaming consoles and high-end graphics cards. On top of its gaming features, it also has extra perks designed for everyday use, like a USB-C port with DisplayPort Alt Mode support and 90W of power delivery, as well as a KVM switch. As it's an OLED display, it's prone to permanent burn-in when exposed to the same static elements over time. It includes some settings to mitigate the risk of burn-in and has a custom heatsink to dissipate heat without a fan.
Our Verdict
The MSI MPG 341CQPX is fantastic for PC gaming. It has a 240Hz refresh rate with VRR support, and motion looks incredibly smooth thanks to its near-instantaneous response time. Your inputs also feel responsive, as it has low input lag. Additionally, it's incredible for gaming in dark rooms as blacks look deep and inky, and bright colors are vivid. However, deep blacks look purple in brighter rooms, and it has distracting VRR flicker when frame rates change rapidly.
Sharp motion thanks to near-instantaneous response time.
Perfect black levels in dark rooms.
Supports all common VRR formats.
Highlights pop in HDR.
High 240Hz refresh rate.
Noticeable VRR flicker with changing frame rates.
Black levels rise in bright rooms.
The MSI MPG 341CQPX is fantastic for console gaming. It has HDMI 2.1 bandwidth and is fully compatible with the PS5 and the Xbox Series X|S, but the consoles don't support ultrawide gaming, so you'll see black bars on the sides. Because of its near-instantaneous response time, it delivers a very crisp image, and its low input lag creates a responsive feel. It also displays deep blacks in a dark room, so it's great if you're gaming in a darker environment. However, if you're in a brighter room, deep blacks look purple.

The MSI MPG 341CQPX is decent for office use, but there are some limitations. Its large, wide screen makes it easy to open multiple windows next to each other. However, while it works well with a few lights around, it doesn't get bright enough to fight strong glare. Additionally, its subpixel layout makes text appear slightly less clear than some other 27-inch 1440p monitors. Also, OLEDs like this one are prone to burn-in with constant exposure to the same static elements over time.

Decent reflection handling.
Extra productivity features, like a KVM switch.
Wide viewing angles.
Text has a bit of fringing.
Doesn't get very bright in SDR.
Risk of burn-in with static elements.
The MSI MPG 341CQPX is excellent for media creation, but it has some limitations. It displays a wide range of colors and has impressive accuracy before calibration. Its ultrawide screen allows you to view more of your work area at once, and its wide viewing angles are great if you need to share the screen with someone next to you. However, its curved display isn't ideal if you need to view straight lines, and text has a bit of color fringing. Another major downside is that it runs the risk of permanent burn-in when exposed to the same static elements over time, like if your editing programs are open all the time.

Differences Between Sizes And Variants
We tested the 34-inch MSI MPG 341CQPX. It's one of several monitors in MSI's lineup that features a QD-OLED panel, including the very similar MSI MEG 342C QD-OLED and the MSI MAG 341CQP QD-OLED. However, these monitors have a few differences, as you can see below. The results are only valid for this model.
| Model | Size | Resolution | Refresh Rate | USB-C Power |
|---|---|---|---|---|
| MPG 341CQPX | 34" | 1440p | 240Hz | 90W |
| MEG 342C | 34" | 1440p | 175Hz | 65W |
| MAG 341CQP | 34" | 1440p | 175Hz | 15W |
Our unit's label indicates that it was manufactured in July 2024. We tested it with firmware FW.020.
Popular Monitor Comparisons
The MSI MPG 341CQPX is a 34-inch gaming monitor with a 1440p resolution and 240Hz refresh rate. It's a newer monitor with a higher refresh rate than the MSI MEG 342C QD-OLED, and it competes against similar OLED monitors like the LG 34GS95QE-B and the Dell Alienware AW3425DW. Its 240Hz display is smoother than many previous-generation ultrawide OLEDs, and its QD-OLED display ensures bright colors are vivid. As a result, you don't need to choose between performance and image quality with this monitor. As the name indicates, ultrawide monitors are truly ultra-wide, and whether you prefer the extra width is a personal choice. If you prefer monitors with a more standard width, there are other high-refresh-rate QD-OLEDs with a 27- or 32-inch screen.

The Dell Alienware AW3425DW and the MSI MPG 341CQPX QD-OLED are competing ultrawide QD-OLED gaming monitors. They have the same specs and panel and perform similarly. The main differences come down to features, as the MSI has a USB-C port with DisplayPort Alt Mode to connect a laptop and a KVM switch, which the Dell doesn't have.
The Dell Alienware AW3423DWF and the MSI MPG 341CQPX QD-OLED are 34-inch ultrawide QD-OLED gaming monitors. The MSI is the better choice for most people, as it has a higher refresh rate for smoother motion, HDMI 2.1 bandwidth, and USB-C connectivity with a KVM switch for productivity. However, the Dell is still an excellent monitor, and unless you need the MSI's higher refresh rate, it's a great option if you can find it for less.
The LG 34GS95QE-B and the MSI MPG 341CQPX QD-OLED are both 34-inch 240Hz OLED gaming monitors. The MSI is better if you want the most vivid colors. However, the LG is a better choice if you're gaming in a brighter room, as deep blacks don't have a purple tint in those conditions unlike the MSI.
The Samsung Odyssey OLED G85SB S34BG85 and the MSI MPG 341CQPX QD-OLED are 34-inch QD-OLED ultrawide gaming monitors. For most people, the MSI is the better option, as it has a higher refresh rate for smoother motion, a KVM switch, and HDMI 2.1 bandwidth. That said, the Samsung is an excellent monitor, and if you can find it for less, it can be a great choice.
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.
