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.

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.

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.

HUGE SCREEN! Cool features (Aim assist). Anything MSI I have purchased has ALWAYS been good. You can't beat what you get here for under $400!

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.

A very nice large ultra wide display with helpful features and great picture

Fantastic for the money!! Perfect size for just about anything!! You can wall mount or get universal bases for it cheap! Gamechanger!!

Amazing product and quality, honestly, way better than I expected it to be. Definitely worth the price.

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.

I’ve been using the MSI MAG401QR 40" Ultrawide QHD 155Hz 1ms FreeSync Premium monitor for both gaming and stock market trading, and it has easily become one of the best upgrades I’ve made to my setup (this is my 2nd one to stack next to my 1st one). I purchased the 1st one a year ago and it has been amazing. The 40" ultrawide QHD format is a perfect sweet spot—massive workspace without feeling overwhelming. For trading, it’s a game-changer: I can keep multiple charts, Level 2, news, and order entry open side-by-side without constantly alt-tabbing or shuffling windows. The clarity is outstanding—text is crisp, charts are clean, and fine details are easy to read even during long sessions. For gaming, this monitor absolutely delivers. The 155Hz refresh rate and 1ms response time make everything feel fast and fluid, and the motion clarity is excellent. Combined with Free Sync Premium, gameplay feels smooth with minimal tearing and stutter. Fast-paced games look and feel responsive, and the ultrawide view adds a level of immersion that’s hard to go back from once you’ve experienced it. Connectivity is another strong point. Having DisplayPort, HDMI, USB, and USB-C makes it easy to run multiple devices and keep the setup clean. Overall, the build feels solid, the performance is top tier for the price, and it genuinely excels in both productivity and entertainment. If you want one monitor that can handle serious multitasking for trading and still deliver a high-refresh, responsive gaming experience, the MSI MAG401QR is an excellent choice. Highly recommended.

This is a really nice monitor. I got it because the size works well with a 32 inch I have. The monitor is really nice. I don't use the KVM feature or any USB hub features. It's a monitor, that's what I use it for. Unfortunatly, this monitor came with some damage. I have tried to get Best Buy to help me replace it but, they don't seem too motivated. The store swears it's a marketplace purchase and the the corp number I called said it has to be a Best Buy purchase because the first part of the order number is BBY01. All I know is, I haev until Jan 15 to return it. I am going to use it until then and then I will be sad to see it go. Also, I bought this on sale for $349, I won't be able to find that deal anywhere else now.

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.

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!!

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

Great size, color and resolution is amazing. Definitely a good buy

This product was hyped up and it was spot on! Awesome refresh rate makes this great for gaming - no problems, no issues, would purchase again.

Great monitor and price was decent for the size. Not very many options for flat ultrawides. I'm a photographer. I would like a higher resolution option but this does work great, I'm just being picky

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.
