I've had this since release, I bought mine on Amazon though. I was on an LG C1 48" OLED, but 4K was really starting to kill my performance in newer games. I also have LG 32" 165Hz IPS and VA monitors as well as a similar spec Dell. Coming from that I'm very happy with this monitor. It's obviously not to the level of detail, clarity, darks or colors of my OLED, but I'm daily use and gaming I've come to find that besides darks, it's not that much of a difference. My biggest concern was pixel density, but I honestly can't see pixels unless I stick my face right up to the monitor. I sit a bit further back so it looks great. It's a 144Hz monitor that overclocks to 155Hz. IPS looks great, colors are ok, my AMD GPU definitely adds vibrance to the colors, but you can also do adjustments on the monitor. Performance is great, no smearing, no ghosting, I haven't had screen tearing either, but I'm also running everything well above 60fps with my 6950XT. The stand is good and fairly sturdy. Overall I'm recommend this monitor to anyone looking for something bigger than a 32" or 34". It's size can be an issue on a smaller desk, but you can also just mount it on an arm to get it off the desk.

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.

i guess i can try to rate this. pros monitor it great jammed with a lot of features. and yes this is worth the money i love the fact that the software that you download for this lets you control all the monitor settings and presets and overclock. i got mine overclocked for my gaming. and my 9700xt sync right up with this. with no problem. even has settings for watching movies. a lot of people do not like the stand. but i guess they have a micro desk not sure why its in the way. unless they changed it. also this is a wide screen. it is 40" from top left to bottom right. but the screen it self height wise you could say a 34" cons 1 no info on how to set this up. no videos that i could find on this model to help you out. the button on the bottom right corner is not the power button. i first thought it was a d.o.d i am not sure what that button does yet. the button on the back is the power button and the menu. 2 on mine the usb B would not work. into i replaced the cord. and then it just keeps making the disconnect sound. it finally took thank god but not sure why this was going on. as i have a lot of usb stuff and everything else was working fine. 3 shipping. was slow. 2 weeks but i did get it on the 12th instead of the 15th/23ed was just a bit aggravated cause i am a prime user and this is a amazon sold product. but it was packed good and taken care of. 4. the lights on the back change and all. look cool. but there not bright at all. at least from what i see. there running now and i cant see them reflex off the wall or nothing. so it is kind of pointless. unless i am missing something. i dont look behind my desk so. i well never see them lights in action. over all it really is worth the money. i do like it. once you learn the settings you well not regret this at all.

Still running this as a daily + gaming with 155hz, over my secondary 27" mini-led 180hz. Love the size, great for gaming and productivity- pretty heavy so I used a tv wall mount above my 27" so I can look up a little and correct my neck posture. I rarely even turn on my second monitor anymore, good colors, 3440x1440 make sure your GPU can handle it, and some games may need an ultra wide mod to utilize the full screen. Chrome also has extensions for ultra wides as well that I use for YouTube and any websites with videos.

The size and picture quality of this monitor are pretty decent, super good enough for the price. I really really want to like it, but I just cannot recommend it. I got this because it had built-in KVM and Thunderbolt, and I wanted to be able to switch between my work and personal computer without an additional KVM or dock. Sadly it's kind of poorly executed on both fronts. The Thunderbolt connection to a laptop works fine (with an important caveat), but the interface for KVM is *bad*. There's no way to control which interfaces are active to cycle through, and the whole operation is just clunky. Some of it is helped if you have the MSI software, but that's Windows only, and plenty of people can't install software on their work computers. Now that caveat. The biggest problem with it both as a Thunderbolt dock and a KVM switch is that the USB port it provides for peripherals is USB 2 ... in 2024 they built a monitor with a USB 2 hub in it. I have a fancy webcam that won't even work through it. How much did this save per monitor? A couple dollars? So cheap of them. Also the backlight is now intermittently not working on almost half the screen when it's 9 months old. So I'm not feeling optimistic about its build quality or durability. Having read some other reviews here I'm also not optimistic about MSI's support and warranty process. Stay away.

I adore this monitor! This is the best price-to-quality display on the market. There's no arguing that! I spent about 6+ months keeping my eye on it, and I was fortunate to buy one in mid-October. I wasn't able to set it up until last week. I'm blown away with how rich the colors are for games. I've been playing WoW, The Last of Us Part I, Forza Horizon 5, Oblivion Remastered. They all make FULL use of the 20:9, and it's just incredible how rich the colors are. I just have one TEENY WEENY problem. I have what looks to be a stuck red pixel. I want to know from an expert, someone who has this monitor, or preferably, from MSI, what you'd recommend doing to bring this pixel to life! I believe it is stuck, not dead. It could just be one, or it could be a few in a tight, singular region. Any help would be great! P.S. The screen size finally makes use of my desk's real estate. It's an older wooden desk, and it's large enough to watch movies, from 10-15 feet away! The refresh rate makes video and games look naturally smooth, unlike some screens that tend to make movies look cheaper, less cinematic (at higher Hz). Setting it up was little trouble. The stand is good, though my monitor is slightly tilted, given the off placement of the holes-to-screws.

I really hoped this monitor would work out. Unfortunately mine has flickering vertical lines on the left side. At first it was very infrequent, but after about a week, it's gotten worse to the point that it's unusable. Tried it with multiple cables, a different PC, same problem. Aside from the flickering lines, it has pretty terrible backlight bleed in the corners, with the top right being the worst. I've used many IPS's over the years and this is the worst I've seen, it's bad enough to be distracting even on light images. The included stand is hilariously useless. At first I thought I was somehow putting it together wrong, but no, pictures online are the same. My desk is about 2 feet deep and with the stand all the way to the back edge, it holds the screen closer to the front of the desk than the back. It holds this 3 foot wide display about 10 inches from my face in a normal seating position. The space where the keyboard and mouse should go is also occupied by the long legs of the stand. Get a different stand if you plan to buy this monitor. If you luck out with the QC gamble, this could be a decent monitor. One other thing to note is that the advertised 155hz refresh rate is only available after enabling displayport overclocking in the OSD, and then it switches to a low bitrate mode that looks grainy and terrible. So it's effectively 144hz max. Not a big deal, but frustratingly false advertising.

EDIT: (9/23) Still going strong. Gaming, movies, multi screen shenanigans, nothing fazes this thing. Still can't find a competitor in this price bracket. Thought of getting a second one. Its been great for cyberpunk path tracing at 120fps. 144 in easier to run games. PPI doesn't detract from it either. I was looking at a curved only, but because it's so big, the flat is perfect. Viewing angles also seem to be pretty impressive. My wife can game split screen with me on this pretty easily Seems to be identical to the innocn 40" panel, HDR looks great. Colors are vibrant, brightness is very useable in bright rooms during daytime or night. So far, it's been great for high fps use as well as Ray traced newer games like RE4r. The menu controls work well, and are the typical MSI navigation setup. If it goes on sale, I might buy another one or two and use it for an amazing racing setup. I'm impressed. Exactly the monitor I wanted from Innocn, without the packaging problems leading to delivery damage. Pros- Performance, color, brightness, menu, price($420) IPS, hdr400 144hz, reputable brand, I don't feel like it makes me want a curve because it's so large, super immersive. Cons-only seems to be 144hz instead of advertised 155hz. I'm not sure if it's a mistake on their side, or just hidden in the menu?
