    The MSI MAG401QR 40" Ultrawide QHD Gaming Monitor is an outstanding choice for gamers and professionals seeking a high-performance, versatile display. Its 40-inch ultrawide QHD screen with a resolution of 3440x1440 delivers stunning clarity and vibrant colors, making it perfect for immersive gaming and multitasking. The ultrawide aspect ratio provides an expansive view, ideal for open-world games or productivity tasks requiring additional screen real estate. The gaming performance of the MSI MAG401QR is truly impressive, with a 155Hz refresh rate and fast response time delivering ultra-smooth visuals and virtually no lag, even in fast-paced games like Rust and World of Warcraft. The inclusion of FreeSync Premium further enhances the gaming experience by eliminating screen tearing. Connectivity is another standout feature, with DisplayPort, HDMI, USB, and a highly versatile Type-C port accommodating a wide range of devices. I’ve connected mine to both my Alienware gaming laptop and MacBook, and the ability to seamlessly switch between computers with the press of a button has been a game-changer for my setup. This monitor is ready for buisness and play. The MSI MAG401QR boasts a sleek black design that is modern and understated, fitting effortlessly into any setup. Its adjustable stand provides ergonomic flexibility for extended comfort, while the robust build quality adds a premium touch.

The MSI MAG401QR is a high-performance ultrawide monitor with exceptional features and immersive visuals, making it ideal for gamers and professionals. While its large size may not suit smaller desks, and its built-in speakers might not satisfy audiophiles, these minor drawbacks are outweighed by its seamless blend of functionality and aesthetics, offering outstanding value and a top-tier experience.

    I was nervous getting this online since I was not able to see how it functions before i ordered it, bur it was a great decision! I use this for gaming and it was veen wonderful, good display, crystal clesr imsge. I havent had issues with dead pixels or cheap materials. The stand is higg wuality but if yoy plan to mount it make sure it can support the weight. I have a high quality mount i used for my old 27" curved monitor, it was overkill for that monitor but still wasnt enough to hold this one. I would and have recommended this to others, id argue this is more worth your time and money than the odyssey series.

    Nice image quality, half-baked software and KVM

    I just want to first say that the image quality is very nice and as a monitor, it works well. However, the KVM function is flaky (limited USB), there is only ONE DisplayPort input, and I just confirmed with MSI support that it is not possible to change inputs if the monitor is in standby. Why might that be an issue? Consider this situation: I have my desktop PC connected via DisplayPort (because I want the fastest refresh rate for gaming). I turn that off and the monitor goes into standby. I later decide to plug in my work laptop (fresh Windows install, latest display drivers) into HDMI 1. If the monitor's Auto Scan setting on the source is set to "off", the ONLY ways to wake up the monitor to switch it to HDMI 1 are to either send a signal over DisplayPort (e.g. turn my desktop on) or unplug the power, plug it back in, and quickly open the OSD menu before the monitor goes back into standby. I have never used a monitor that you couldn't manually wake up and change the input. For size reference, the photo is with two 24" 1080p monitors.

    Who says 40 inches is too big?

    This monitor is absolutely beautiful and a steal for the price. At first I was very hesitant to buy it because it was a 40 inch monitor and I thought it’d be massive but after 2 to 3 days of using it, I quickly realized that this was the best purchase I’ve made when it came to a monitor the quality of the picture gaming or just using it for every day use is phenomenal and I could not be happier.

    The Mag401qr is a very affordable monitor for those who want a large monitor but dont want to spend almost $1,000 for one. This monitor has a 40" 2k 155hz screen. Even has a Type C with 65w and you can even download the software to manage the settings without having to use the buttons on the back of the monitor.

    So I got this monitor to replace an old 32 in 4k monitor that would not display past 30 hz on my macbook, I was hesitant to get it because I wasn’t sure it would work and would get the 140hz or the 155hz overclocked dp mode. Well let me tell you that not only runs at 155hz at its full 3440 x 1440 resolution, its color is great. When you first set it up you will have to use an hdmi cable to get it to work but then using an apple thunderbolt cable and changing the monitor to usb c works like a charm. You will have to set the monitor to overclock dp mode to use the 155hz but I recommend setting R and G to 90 and B to 100, contrast to 60 and brightness to 80 to get a very nice picture. This rivals my studio display and I think this will be my main display and have my studio display as backup.

    Exceeded expectations

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    This is just what i needed to fill in the gap of games that dont fully support surround mode gaming. I did do some tweaking to the nvidia settings when hdr was enabled but it has made my games look amazing. I havent tried it with a console yet but my 4080 super works well and i am able to turn on all the eye candy. Currently i am only using it on hdmi because i allready have all the display ports on my card being used. Capped at 100hz is fine though. Ive been playing Returnal and Ratchet and clank rift apart. Both look amazing and play flawlessly. The picture quality is on par with my Acer predator 27 inch displays. I would reccomend this to anyone looking for a 1440p monitor with 144hz or higher expectations in theor games. Text also looks crisp and movies as well. Very satisfied overall.

    Great quality monitor. Nice size, great resolution/display is super crisp and colors accurate. I wish it was curved, but then it would be perfect...gaming one tends to lose the edges when not curved and with such a big size. But so far soo good, happy w/purchase

    To be honest this monitor is top tier! It’s only missing the OLED so I gotta rate it 9.3! Also missing the height adjustment but that’s definitely not a deal breaker for me at least. This has the massive real estate on the screen and it’s not curved and it’s IPS! Super clean I need to get this monitor back I only returned it to try out that new Samsung oled G8. I prefer this monitor over that! The response time is really nice as well you’re getting so much for a monitor under $500! Don’t hesitate if you have the budget for this monitor! Grab it!!

    I got the product for about 430 after tax. I wasn't sure how I'd feel about a 40" ultrawide, but it really helps when I'm doing tasks on the desktop and it's great for playing games when paired with my setup. No problems with screen tearing so far playing No Man's Sky or Black Myth: Wukong.

    I wasn't sure about this monitor because of it's size, but I am very glad I gave it a shot. I feel kinda bad about not having a ultrawide before this, but it's a great excuse to load up some previously played games. I can't imagine going back to a 21:9 setup after this!

    The ultrawide on this monitor is nice but since it is flat, it’s a bit too wide. If the monitor was curved, it would be more useful for me. If this was for photo or video editing, it would probably work. For the price, it was great, I just opted for a curved ultrawide.

    This is a really good monitor, great for the price. Just be aware that the USB hub is separate from the usb-c that powers your laptop and sends video signal. Not a problem if it's hooked up to a desktop but if you switch out your personal and work laptops and want your wired accessories to stay usable with whatever computer is plugged in.

    This was the only good IPS ultra wide I could find that wasn’t discontinued I would implore anyone interested in getting an ultra wide monitor for gaming or work to get this one it’s worth every penny only gripe I have is the stand that is included is not adjustable so you will need a third party mount to have it higher, tilt left and right up and down all that don’t worry about it being a 40 inch just buy a mount that supports the monitors weight without the stand and have a sturdy desk to mount it on!

    Great monitor at a great price. This is about the least expensive wide monitor you can get with all the "bells and whistles" for this price. It has the FreeSync that allows game play, can be set to quick response time with some setting in the menu, lots of color adjustments, and so much more. I have this connected with a USB4/Thunderbolt cable to my laptop and it works perfectly. If you do not want a curved monitor, this is the best deal. My only "gripe" is the stand. With the included stand, the back of the monitor is about about 5 or 6 inches from the furthest back you can place the stand on the desk. Not a huge gripe, but keep that in mind when selecting this. you may want to get a different (VESA compatible) stand so you can move the monitor further away without it falling off the back of the desk.

    This monitor is great for computer gaming and video editing. It has worked really well at the stated 1440 p at 144hz. However, mentioned no where in the listing is that through hdmi it isn’t 2k it’s actually 4k at 60hz. Which is absolutely perfect if you have any intention of using a gaming console.
