The MSI MAG401QR is a 40-inch UltraWide Quad HD gaming monitor aimed at PC players who want wraparound immersion without jumping to a curved or super-expensive display. With a 21:9 aspect ratio, IPS panel and up to 155Hz refresh rate, it’s built to show off modern titles at their best.
MSI is well established in the gaming monitor space, and this model sits in the sweet spot of offering enthusiast-level specs without straying into flagship pricing. Owners rate it very highly, with an average user score of 4.8 out of 5 from a growing number of reviews, suggesting the experience largely lives up to the promise.
On paper it’s a strong all-rounder: a huge flat ultrawide canvas for games and multitasking, responsive performance for fast-paced titles, and a sprinkle of RGB with Mystic Light for building out a themed setup.
The MAG401QR is ideal for PC gamers who want an ultrawide upgrade that genuinely changes how games look and feel. The 40-inch, 21:9 UWQHD panel gives you a broad field of view that works brilliantly in racers, RPGs and open-world adventures, and the 144–155Hz refresh rate makes it fast enough for shooters and competitive titles too.
It suits mid-range to high-end gaming rigs that can comfortably drive 3440 x 1440 at high frame rates. If you have a powerful graphics card and want to see what it can really do, this is the kind of screen that makes the investment feel worthwhile.
The large, flat panel also makes sense if you work from home or multitask heavily. There’s ample room to park multiple windows side by side, and the IPS viewing angles mean it still looks consistent if you’re not sat dead centre. Content creators and hobbyist video editors will appreciate the wide colour coverage (DCI-P3 and 118% sRGB) at this price point.
It’s less suited to tiny desks or very tight budgets. At 40 inches wide it demands a decent amount of space and a sturdy stand or VESA arm. If you mostly play console games or sit further back on a sofa, a more traditional 16:9 TV or monitor may be a better fit.
The 40-inch ultrawide UWQHD resolution (3440 x 1440) is a real highlight, delivering loads of on-screen real estate with crisp detail and a wide 21:9 field of view for immersive gaming and productive multitasking.
The fast IPS panel, 1ms response time and up to 155Hz refresh rate combine for smooth, responsive gameplay. Motion blur is kept in check, which is especially helpful in competitive shooters and fast racers.
Adaptive-Sync support helps reduce tearing and stuttering when your frame rates fluctuate, giving a more consistent experience without having to lock the refresh rate.
MSI’s Mystic Light RGB adds a bit of customisation flair, letting you match the monitor’s lighting to your PC, keyboard and other peripherals for a cohesive setup.
The feature set is rounded out by practical touches: anti-glare and anti-flicker technologies, blue light reduction for more comfortable long sessions, a built-in USB hub for easier cable management, and VESA mounting support if you prefer an arm.
There are no built-in speakers, so you’ll need separate speakers or a headset for audio, which adds to the overall cost and cable clutter.
Peak brightness of 250 nits and basic DisplayHDR 400 support mean HDR is present but not particularly punchy. You’ll see some benefit in contrast and colour, but it won’t match higher-tier HDR displays.
The stand only offers tilt adjustment, with no height, swivel or pivot options. On a 40-inch panel that can be a limitation unless you use a VESA arm or have a flexible desk setup.
Connectivity is solid but not cutting edge, with HDMI 2.0b rather than the newer 2.1 standard. That’s perfectly fine for PC use at 3440 x 1440, but less ideal if you were hoping to use it with next-gen consoles at their highest feature set.
Living with the MSI MAG401QR, the first thing you notice is how much screen you have to work with. The 94.6 cm width gives games and apps room to breathe, and the anti-glare coating stops reflections from becoming a distraction in brighter rooms.
The flat IPS panel with 178-degree viewing angles means colours and contrast remain consistent even if you’re slightly off-centre, which is handy if you enjoy couch co-op at a desk or lean back in your chair. Blue light reduction and anti-flicker technology help cut down on eye strain during long evenings of gaming or work.
Setup is straightforward: you get DisplayPort 1.4a and two HDMI 2.0b inputs for PC and consoles, plus a headphone jack for easy headset plug-in. The detachable stand and 100 x 100 mm VESA mount give you flexibility if you prefer to mount it on a monitor arm for better positioning.
Day to day, the built-in USB 2.0 hub is handy for tidying cables by plugging in dongles and low-power peripherals directly into the display. Mystic Light lets you dial in the RGB to match your case lighting, but it remains a background extra rather than something you need to fiddle with every time you turn the PC on.
Performance-wise, the MAG401QR ticks the key gaming boxes. The 40-inch, 3440 x 1440 IPS panel offers sharp detail and plenty of workspace, while the 21:9 aspect ratio pulls you into the action. It’s a particularly strong match for cinematic single-player games and simulators that support ultrawide resolutions.
The quoted 1ms response time and 144–155Hz refresh rate mean fast-paced titles feel fluid and responsive. Combined with Adaptive-Sync, you get reduced tearing and ghosting compared with standard 60Hz screens, assuming your PC can push the frame rates.
Colour performance is solid for the category. Support for 1.07 billion colours, DCI-P3 coverage and 118% sRGB makes it a good fit for light content creation and photo editing alongside gaming. The contrast ratio of 1000:1 is typical for an IPS panel, offering decent shadow detail, while MSI’s Night Vision feature helps lift dark scenes in games without nuking the entire image.
On the feature side, HDR400 support gives you a taste of high dynamic range in compatible games and streaming content, adding some extra pop to highlights and colours. Just temper expectations: at 250 nits peak brightness, it won’t deliver the dramatic HDR impact of more premium, brighter panels.
Practical extras include the Gaming Intelligence app integration for easier on-screen settings tweaks, a Kensington lock slot for security in shared spaces, and a 3-year manufacturer warranty for peace of mind. The absence of both AMD FreeSync and Nvidia G-Sync branding in the spec suggests basic Adaptive-Sync rather than full certification, but for most users it still does the job of smoothing out frame delivery.
At its current price, the MSI MAG401QR sits as a strong mid-range proposition in the ultrawide gaming space. You’re paying more than for a basic 27-inch 1440p display, but you’re also getting a significantly larger canvas, a higher level of immersion and a spec sheet that leans into both gaming and productivity.
The combination of 40-inch UWQHD resolution, high refresh rate, IPS technology and a decent spread of gaming features would usually command a noticeable premium. Here, the balance of features to cost feels well judged, especially when you add in the 3-year manufacturer warranty.
User feedback backs up the value story: a 4.8 out of 5 average rating indicates most buyers are very happy with what they’ve received for the money. The compromises it makes – modest HDR, no speakers, basic stand – are sensible ones that many PC gamers can easily work around.
If you want the biggest, brightest or most advanced HDR ultrawide on the market, you’ll need to spend considerably more. But for a large, fast, versatile 40-inch gaming monitor at a sensible price, the MAG401QR represents very good value.
The MSI MAG401QR is an excellent choice if you want to step up to a truly large ultrawide gaming monitor without emptying your wallet. It delivers a big, sharp 40-inch UWQHD image, high refresh rates, fast response times and useful gaming features that will satisfy most PC players.
Its limitations are sensible and easy to live with: HDR is entry-level rather than spectacular, there are no built-in speakers, and the stand could offer more adjustment. None of these undermine the core strengths of the panel, especially if you already use a headset and are happy to tweak your setup with a VESA arm.
If you’re a PC gamer or power user looking for a flat 21:9 display that can handle everything from esports to sprawling open-world games, while also making day-to-day work more comfortable, the MSI MAG401QR is a very strong contender and well worth shortlisting.
