MAG401QR, 40" Gaming Monitor, UWQHD 3440x1440 Resolution, IPS Panel, 1ms Response Time

This monitor is kind of a stealth deal. A 40 inch, IPS ultrawide for less than half of most of its competitors. Almost all of which are VA panels. Whether it's flatness is a pro or con to you, it depends. I don't mind it. But I've never used a curved monitor. There isn't much difference between this IPS and my old 1080p Asus Designo 27in in terms of colour accuracy and it has the benefit of higher refresh rate. I play a lot of Driving/Flying/Train sim games and some other genres as well and this monitor is perfect. Very immersive experience at the distance it sits from me. The contrast ratio is really good for an IPS without crushing the blacks and the light bleed is fairly uniform and unobtrusive. I didn't notice any ghosting, though I'm sure it exists. The stand is well-engineered, perhaps even overengineered. It's very solid, but requires eight screws in total to assemble. The tilt....works but it's extremely tight and does not tilt down. Also my panel had absolutely no dead pixels! Cons: Mystic Light LEDS are so dim they might as well not exist. The navi button broke within an hour of owning the monitor and I somehow shoved the whole thing into its hole with not much force, making the OSD useless. Luckily, this monitor will accept MSI's gaming OSD software which has all the onboard OSD functions anyway. So this is really largely a non-issue and I didn't want to RMA a 40 inch widescreen, that'd be a headache. sRGB mode looks fantastic, the other modes tend to lean towards heavier saturation. If you LIKE saturation-forward stuff, this monitor is great. However if you're going to stick in sRGB mode for artwork for the accuracy, the nits are somewhere between 300-350ish and that's a little dim. You can get closer to 400 by cranking the brightness but that'll start washing stuff out and balancing it with contrast and such will heavily saturate. I like heavy saturation while gaming and the lower brightness doesn't bother me too much in this space. But in a bright room, it could be annoying. However for the cost, expecting a 400+ nits display is a little ambitious.

This monitor is seriously great. I was torn between a handful of ultrawides but opted for this one as going to larger panels (49" and above) results in less vertical space and more horizontal space. Transitioning from my previous 32" 1440p panel to this was a breeze as they essentially share the same height. I like this monitor enough that I have a second one on the way to stack them up for work. Only glaring downside to be found is the stand is abysmal. Seriously. Don't buy this unless you also plan to grab a mount or have one that can support this panel, but a serviceable one can be had for $30-$50. Side note: I'd avoid any monitor mount that has a quick disconnect feature where the monitor connects to the arm via the slide and thumbscrew design, as the weight and size of this monitor will most likely cause a small amount of droop at the connection that is hard to alleviate. There are a lot of these out there, so reading assembly instructions or looking at customer photos/product photos first will save a lot of headache. I would opt for a simpler design that directly connects to the back of the panel via screws or go premo and get an Ergotron or similar quality arm. I'm currently using VIVO mounts, specifically the ones that mount the monitor to the plate w/ 4 screws and have had no issues with droop or sagging. (STAND-V001T for reference) OSD menus are fine, if a little slow to navigate, but you're going to most likely set it up once or twice, and then rarely, if ever, dive back in. Picture looks great in SDR and has almost eye searing brightness at 100%. IPS panel is actually an IPS-ADS panel made by a company called BOE. There are some alleged refinements over a traditional IPS and while I'm not at liberty of being able to make a direct comparison, I will say colors, viewing angle, and motion on the panel look great. No perceived ghosting for myself, personally. No backlight bleed whatsoever and that's highly impressive to me as I had a few years run with VA panels instead because I got sick of playing the IPS lottery. I can't make any claims about HDR as it's not important to me for gaming or work. If you're looking for an HDR monitor, based on the HDR400 spec alone this probably will not satisfy, but it's more of an extra feature than the main event and while Win11 brings lots of autoHDR goodness, I'm still not convinced about leaping fully into HDR. USB-PD and KVM switch is super neat to have onboard, and while I haven't needed either just yet, I have plans to utilize these soon. Overall, it's an exceptional panel with a wealth of functional, full-baked features. I think it strikes a great balance of price/performance. While it may not have the most bleeding edge panel tech like QD-OLED, and it's no HDR beast, and the stand is absolute nonsense, I think there's a lot to like here for $400, and even more when it's priced at its current $350.

lo compre para hacer Home Office, me encanto, pero tenia que mover la cabeza demaciado por el tamaño, tuve que devolverlo por que no era funcional y comprar uno curvo mas pequeño 34'', pero por el precio que lo agarre y la calidad, lo volveria a comprar

When I first powered on the MSI MAG401QR, I was genuinely disappointed. My desktop background looked pixelated and unimpressive for a monitor boasting UWQHD resolution. But here’s the trick: search for a proper 4K theme. Once I swapped in a high-res wallpaper, the transformation was instant—crisp, vibrant, and beautifully sharp. The IPS panel truly comes alive with the right content. Now, for desktop office use, brace yourself: the ultra-wide 40" screen can feel overwhelming at first. I actually had a bit of neck strain from constantly turning my head left and right to take it all in. It’s like sitting front row at a cinema. But after a few days, your posture adapts naturally, and it becomes second nature. You start appreciating the extra real estate—multiple windows side by side, immersive spreadsheets, and a workspace that feels expansive and efficient. Gaming is where this monitor really flexes: 155Hz refresh rate, FreeSync Premium, and HDR400 deliver smooth, immersive visuals. But even for productivity, once you settle in, it’s hard to go back to anything smaller. And one last tip: take the time to adjust the monitor’s settings. Tweak the brightness, contrast, color profile, and sharpness to your liking. Once dialed in, the display quality becomes truly impressive, rich colors, deep blacks, and razor-sharp text. It’s a game-changer.

Para el precio, 40 pulgadas uwqhd (3440x1440) está muy bien, es un IPS a 144hz que se puede hacer OC a 155hz (120hz con cable USBC) personalmente no lo hago ya que la diferencia no de nota y te bloquea algunos settings del monitor, HDR también es bastante bueno. El monitor es GRANDE, no lo aparenta en las fotos pero lo es, así que necesitas un escritorio o un área grande para disfrutarlo. Totalmente recomendable ponerlo en un brazo al escritorio o a la pared ya que la altura es estatica. Cómo opinión personal, si tienes una tarjeta de video que soporta resolución dinámica, pon una resolución mayor y creo que se le saca mejor provecho , yo lo tengo en una PC con una amd 7900xt y lo tengo a una resolución de 5120x2160 y me da la impresión que se disfruta mucho más el tamaño real del monitor. Si fuera curvo sería un plus bastante interesante pero no es necesario. Ciertamente se calienta un poco pero nada de que preocuparse 100% recomendable
