AOC CU34G2X 34" Curved Frameless Immersive Gaming Monitor, UltraWide QHD 3440x1440, VA Panel, 1ms 144Hz Adaptive-Sync, Height Adjustable, 3-Yr Zero Dead Pixels, Black/Red

This review is for the 34" CU34G2X UltraWide QHD 3440x1440 monitor. Used for about a week before writing this. This is the best monitor I've ever seen with my own eye's! The curve is perfect, not too much, not too little. It's really immersive for gaming in particular. And for reading online and working for long durations the curve still looks great and is not distracting. Looks amazing on its own, even without content! Solid metal stand and wide metal feet. Very sturdy. The metal feet have lots of solid, grippy rubber pads on them so it stays right where you put it. The screen isn't too glossy or too matte. The red trim is well placed and not over done. It looks very modern and professional, but still calls attention to itself like a gaming monitor should! Refresh rate does indeed go up to 144hz no problem in games and in Windows 10. Color reproduction is really good to my eyes. They include a printed sheet with the color calibration results for your specific monitor with serial number, so AOC really is going the extra mile to prove that these really are high-end monitors. This is a super low latency "VA" type panel. So it is the best looking panel type from a technical and color reproduction perspective. IPS panels traditionally had lower refresh rates than VA panels, but this monitor proves you can have the best looking VA panel type, AND super low 1ms refresh rates. Games look amazing in the ultra-wide format. Halo on PC for example actually gives you a full field of view with this monitor, same with Rocket League. So you do actually get an advantage in some games. You literally can see more of the field of play with the ultra-wide aspect ratio 21:9, than anyone else stuck on the 16:9 ratio that most 1080p or 4k monitors use. Brightness is great, even too bright at highest settings unless your in a really bright room. So that's nice to have if it's needed. All brightness and contrast settings and even gaming profiles are adjustable through physical buttons under the monitor, but also through the G-menu software. So using the G-menu software you don't need to fiddle with the physical controls of the monitor at all to fully adjust and control the monitors settings. G-menu even has hot-keys so you can change your monitor settings to different profiles almost instantly. You can download the G-menu software from AOC's support website. Make sure to use the included DisplayPort cable with this monitor. The HDMI ports don't have the same capabilities as the DisplayPort connectors. To get freesync, 144hz, and native 3440x1440 resolution all together; you MUST use either of the two DisplayPort connectors on this monitor. AND make sure your not just converting from HDMI at the source to DisplayPort. The source signal from your PC also needs to be DisplayPort. There is also a usb3.0 cable included. You can use it to hook it to your computer, then you can use the monitor as a USB 3.0 hub. Power Delivery is off by default on the USB 3.0 ports, but you can enable it via the monitors settings menu, or through the G-menu software. Amazing monitor, highly recommended.

If you've been wanting to make the plunge to 21:9 Ultrawide but don't want to spend 700 to a 1000 (entry, some are double the price), this is the monitor. I got mine for $370 on black friday, but the mid $400's they are current asking is still a steal. First off, the specs are out of this world and they hold true. 3440 x 1440p is the best resolution you can get without going 4k, and with 4k you need a proper rig to run games at decent FPS. Check your CPU tho, if it's older it might struggle a bit with this res, but not much. 1ms response time is pretty much best available, the 1500R curve is simply the best balance between a nice curve and not feeling like you are surrounded. It's not flat, but appears somewhat flat while viewing, but there's just the right amount of curve. The colors are nice, very accurate. Doesn't quite pop like an IPS panel, but it looks fantastic. Even in mid 2022, 1440p gaming is still considered the sweet spot unless you've got the budget for a $300 CPU and $1,200 GPU, not counting RAM, MOBO etc... The onboard controls could be a tad better, and are difficult in low light until you memorize the button patterns, but that is easily forgivable. The brightness is well bright, I never go over 70 even in a well lit room. Overall, I can't say enough about this monitor, AOC really hit it out of the park with this model. It's kind of been glossed over by the thousands upon thousands of dollars for an LG or Samsung, and that's a shame, because AOC should be praised for what they've done here. No dead pixels, everything has been beyond smooth, easily the best monitor I've ever owned, I'll NEVER go back to a flat panel. Oh and did I mention this thing is 34 inches? Most monitors with these specs are 1080p 27 flats, or maybe a 32 if your are lucky. As a gamer for over 20 years, I promise, do yourself a favor and pick this bad boy up.

Needing a replacement for my damaged ultrawide monitor, I picked this one as a step up. It's NOT full 4K, but given the 1)size, 2) curve, 3) relative price, this monitor seemed like a good value. Also, I have owned AOC (not the Congressperson) products before, so I was not expecting to be blown away or anything, and to have some complaints, but also I was expecting something that did the thing it was supposed to do. Quick takes: 1) Not an ultra-precise display for color or all viewing angles (I mean, if you need ULTRA perfect), but if you're looking for that, you wouldn't consider this price-point anyway 2) 100% great for general desktop use and gaming-- sitting at the center, color and brightness are uniform from edge-to-edge, and normally-imperceptible color variation from top-to-bottom (you will see it with some colors during a manual calibration, but not normally otherwise) 3) Be prepared to make a lot of adjustments to the monitor's settings in order to get the picture where you want it-- AOC does themselves a disservice shipping it the way it's set, as many out-of-the-box users are going to be confused and disappointed, I expect. So, out of the box, the monitor is pretty substantial-- it has a heft and build quality I'm used to seeing in more expensive monitors. Setup is as easy as you'd expect for any monitor these days. I used DisplayPort, but the monitor also has HDMI inputs also. Right away, though, I could see something was off about the monitor's settings, which isn't a huge deal, because you can just change the settings, right? Well, yes, but... this monitor insists on having the MOST HORRIFIC combo of on-screen display and small, identical-feeling, hidden control buttons. Getting around the OSD menu is a nightmare of accidentally exiting menus, turning the monitor off, and paranoia about pressing the wrong buttons. One thing, right off the bat, that was extra-confusing is that (despite what some of the listing info says above this monitor DOES have HDR). However, turning it on in Windows immediately makes the picture entirely washed out, giving me a new starting point to calibrate and to question the sanity/value of HDR (honestly, with it turned on in Windows and on the monitor, I can't see a big difference, but just some odd behavior in games sometimes.. not even sure why). I'm not a pro at calibration, but I get the basics and, walking through some online manual (as in, by-hand) calibrations, I both learned a lot about the display, and got the picture to a decent place-- it's annoying the default settings didn't start closer. I was able to get it to a place I like-- others have said things about the brightness, but I've had no issue-- I've had to turn my brightness down a bit to get it to a comfortable place. Anyway, I recommend it, just know what you're getting into.

AOC CU34G2X 34'' (just 2 days of use, and I'm writing this review only for colors and the color and performance of this monitor so far.) The colors of the monitor are great after some adjusting, download the software of the AOC website, don't bother with the buttons on the display, they are like tires on a chopper lol. The customization diversity of this panel just makes me emotional, only if u knew how much time I spent on my previous monitors for color adjustments. It comes factory calibrated, with a bit brightness and contrasts adjustments, it definitely looks much better than my 27inch IPS HD(400) monitor ever did. After trying IPS, TN, and VA panels, I can say that I definitely prefer a Va panel for gaming and movies. This monitor also gives color profile options for reading and other types of tasks. I've read and researched a ton about panel types, functions, and anything that distinguishes one monitor from another. Almost everyone has said that if you care about colors pick IPS, and TN if you care about performance, and VA is just something in between. I can say that because of their internal structure, It seems to me VA panels look much more vivid, easy to see and distinguish what is happening in a video or game much better than other types. I think if you are like me, who wants colors to pop up, the details in a small picture to be as colorful and vivid as when they are in full picture mode, you should try a good VA panel. And This panel so far didn't disappoint, I tried a week, and couldn't get a picture on a 1440 IPS panel to pop as in this 1440p VA panel. I played with settings of this monitor for about 20 minutes and it looks better than the 1440p IPS panel ever did. There are lots of settings to adjust colors, brightness, picture mode, and contrast. Not even some very expensive panels don't allow you to adjust as much as this monitor lets you. The game performance is pretty good, the colors are good, I've no complaints so far. I definitely recommend this monitor to everyone. Update: I was really happy with this monitor until I started to play some fast first-person shooter games. Unfortunately like most VA panels, this panel also has smearing during fast movements. I'm not sure how that is possible on a 1ms monitor, but it is quite bad if you would like to have responsive gameplay.

When I first got the monitor hooked up, I did run into some issues. Not the monitors fault, but I'd like to share my experience in case anybody else is having the same issues. I have a GTX 1080ti, and when I rebooted my computer for the first time, I got a VGA error QLED light on my motherboard. After about 2 days of on and off tinkering, I learned i needed to update my GPU Firmware. Not the driver, but the firmware. So just a heads up if you're having that issue. Again, not the fault of the monitor whatsoever but just an incompatibility somebody else might experience. If you're using a newer card though you shouldn't have any problems. This is my first 1440p or Ultrawide, so my enamor at this monitor could definitely be that I didn't know what I was missing, but after tinkering with some picture settings (there is software to access the menu from windows if you hook up to USB) I found the picture and color to be good enough. I do mild amounts of video and photo editing, and color accuracy didn't seem like it was off in any noticable-to-me way.The slim bezel is good enough for my standards as well, and I like that it uses both a standard power cord straight to the monitor, and plain old HDMI and DisplayPort. I've also been working from home, and the extra screen width is so nice to have. I'm able to have 2 email accounts up and a text based web page, up on the left side of the screen, and on the right, a youtube video playing using a popout player extension, and a word or excel document. I highly recommend installing PowerToys from microsoft and setting up the fancy snap sections. If you're a gamer who is considering getting an ultrawide, this monitor is well worth it, at the $450 price point IF you can find it for that price. Plus a USB hub built in is always nice.

This monitor checks all the boxes for a gaming monitor at a great price that also doubles as a productivity enhancing second screen for work. Curved display is functional at this width without being too severe. Default settings need to be adjusted for best display. I can easily have two browser windows open side by side without them being too narrow. Games look great. The first one only lasted 6 months. Powered up, but zero display. Not even the "no input" message window. AOC support said it was defective and it was covered under warranty, and instructed me to contact them via support form on their site (seems simple enough). I did so, and received an email asking for some info about the monitor. I responded, then nothing. I responded to the same email several times, and nothing. So I called back and was told to follow the same process. In the end, I had to call 4 additional times, and send another support form, which required me to resend all the same information. From the time the monitor broke to the time I finally got my shipping label it took almost 2 weeks. Once I finally received it, I needed to go to a UPS store and pay another $30 out of pocket to have the monitor boxed and sent back. The shipping was covered, but not the packaging. If only I knew I would need it 6 months later, I would have kept that enormous box it came in and saved myself $30. After I shipped it out it took 3 and a half weeks to then receive a replacement monitor. That amount of time isn't too bad considering, but it sure was a hassle to make it happen. So far the new monitor looks fine, no dead pixels. We'll see how long it lasts. In the end, I paid about $450 for a monitor that worked great for 6 months, then had to jump through a ton of hoops, deal with some seriously unfriendly support folks, pay more money out of pocket, then wait another few weeks to finally get back to where I started. It's a good monitor, but at this price, it's not worth taking the risk of getting a dud.

I felt compelled to leave a review that primarily speaks to my experience w/ the warranty after seeing some other reviews. Monitor is great. This was my first 34" ultrawide. I originally purchased in March of 2021 to complement a new pre-built I purchased due to lack of GPU inventory to build myself. Fast forward, 6-months later and the monitor fell face forward on my desk and caught the mouse in the wrong spot. Oddly enough, this cracked the screen in the upper right hand side thus damaging the panel and rendering a 6-inch space in the shape of a rectangle from the edge inward blank. The rest of the monitor worked, but seeing this happen almost brought me to tears given the expense and short lifespan. This happened on a Sunday. I contacted AOC via email that night, but decided to call in the next day in the evening. I connected w/ a rep and he helped get me started. The rep sounded French and it kind of reminded me of a scene from the IT crowd where one of the characters calls into a call center and has difficulty understanding the agents. Regardless, he was very helpful and able to get the process started for me. Once started, as a customer I had 2 choices to proceed w/ the replacement (one of which the agent alluded to taking a bit longer than the other, though not specific to which one). I could either opt to ship the monitor myself and a replacement would be sent upon receipt OR provide my CC for them to ship one out ASAP, which I could then use the box to ship the damaged monitor back. I opted for the path of least resistance, which to me was providing my CC info for them to ship me a monitor ASAP. The process was initiated on a Monday evening. I received a follow-up from the warranty processing company on Wednesday letting me know it had been approved and giving me the choices on how to proceed. I promptly submitted the info. I received a notification the order had been placed and I'd get a shipping notification upon the replacement monitor being shipped. About one week passed and I hadn't heard anything. I checked the RMA website that same day (following Thursday after RMA had been approved) and saw nothing, but finally got an email notification that the monitor had shipped. When i checked the tracking, it was set to arrive the following day. It arrived that next day as expected and I'm typing this from the same computer/monitor setup. The whole process from initiation to receipt of the monitor took just under 2 weeks (about 10 business days). I was really impressed with the AOC warranty and the speed and relative ease at which I was able to adhere to their process and get a replacement. This was a first for me, as I typically don't like to rely on warranties. I learned 2 lessons from this: 1. A warranty like the 1 year AOC warranty makes ALL the difference in the world when you need it AND is something I will be on the lookout for in other monitor purchases. 2. Maybe I should think twice about purchasing an extended warranty for an expensive monitor. THANK YOU AOC

It's 4k, 144hz all at a reasonable price. With Quarantine beginning in March 2020, I was looking to upgrade my home office in order to increase productivity... Okay okay, also for gaming and watching movies, but I swear it, for work productivity mostly. The AOC 21:9 ultrawide monitor now serves as my primary and it provides enough screen to substitute for a second monitor, though I still keep a second monitor on the side and am thinking about putting another one on top. the colors are great and I don't see any ghosting or light bleed on this monitor. I will say that this Monitor is far from frameless as I understand it, the bottom of the bezel is wider at the bottom than my other "bezeled" monitor. Another gripe I have is the display buttons to setup and control the display, they're a little unintuitive but more cumbersome to use... thank goodness I really only have to set up the monitor once in a blue moon. I purchased this on a really hot deal for $450 and it is one of the better deals for a premium quality ultrawide monitor at the time of writing this. It is rare that this monitor comes to that price, but if you do see it get that low again, I would say that it's a must buy for anyone looking for an ultrawide monitor.

Excelente monitor que ha superado mis expectativas. Recién adquirí una RTX 3070 y tenía curiosidad por estos monitores Ultrawide más panorámicos y su tecnología AdaptativeSync en el caso de Nvidia. Tenia temor por el issue conocido de parpadeo en ciertos juegos y pantallas de carga pero no he tenido ningún problema y la tecnología Sync have que los juegos se sientan más estables y fluidos en cuanto a FPS, y esto no pasaba con mi anterior monitor convencional 4k a 60 hz. Yo compré aparte un cable DP 1.4 ya que no estaba seguro si lo traía el monitor, si lo trae pero solo es 1.2 así que si lo quieren usar a máxima resolución y 144 hz les recomiendo comprar uno de máxima calidad. Cómo área de trabajo es enorme!! Vengo de un monitor de 28 pulgadas u de inmediato se nota la diferencia y se presta para acomodar nuestras herramientas de trabajo juntas. Para obtener la mejor calidad de imagen busquen configuraciones para implementar el Picture boost y activar el ASync. Super recomendado a buen precio ($10800)

Be careful when reading the reviews here on Amazon this page has several monitors on it, I'm reviewing the 34 inch 21:9 CU34G2X. I compared this monitor side by side with the LG 34GP83A-B, Samsung C49RG90 and Acer XB273K, it has by far the best quality per dollar. The only area the other monitors were noticeably better in was brightness, this monitor is bright enough but just not super bright like those 3. I work in a very bright room and it's good enough, the bright frame feature helps a lot here. There is a great description of how to calibrate all the settings on Reddit by collective_dysentery, just search for "cu34g2x calibration" and you'll find it. I recommend using that as a starting point then tweaking to what works for you. The colors were also better on the other 3 out of the box, especially the LG and Acer which are IPS, but I found that it was pretty easy to use the controls to get them close to the same level. This monitor has much better contrast than the LG of Acer which I found made a much larger difference to image quality. The Game Color feature is nice for giving colors some extra pop for games, for work I found leaving it at the default 10 to be the best however. This monitor has by far the best anti-glare of the 4, I do not notice any significant blurriness on small text. It seems to be a tiny bit less sharp but nothing worth worrying about. The XB273K was much sharper of course as it's 4K. I found the 1500R curve to be really helpful for making the edges of the screen useable and the curve only took a few hours to get used to. Even though the XB273K is not as wide and 16:9 it was noticeable how far away the edges are on it. At 34 inch 21:9 a flat panel would have unusable edges. Shadow Control works really well for adjusting how dark/light the shadows are in a game, if you want that dark game ambiance with deep blacks and tons of contrast just drop the Shadow Control down one or two notches. I have not noticed any brightness flickering from G-Sync in games, it did happen in Amazon Workspaces that I use for work but that's easily solved by turning off windowed G-Sync or temporarily turning it completely off. There is absolutely no reason to use G-Sync in work applications like Workspaces. The build quality is very good, the best of the 4, although they were all well made. All 4 of the monitors I tried are great units I would recommend any of them to anyone, for me the AOC CU34G2X just made the most sense even mostly ignoring the cost. If the Samsung C49RG90 was $800 or less I would have went with it because of the extra screen space of 32:9 and higher brightness but even at that price it would be close. It's not curved enough so the edges aren't usable and it's just massive.

I've been using this monitor for the last few months now (bought in August, reviewed in December) and think I can now properly list its strengths and weaknesses. Pros: - Massive amount of screen real estate. - Great for work when you need to have multiple windows/apps open side by side. I work in software QA and amount of space as certainly made a positive impact. - Gaming is a good bit more immersive thanks due to not only the wider image but also the slight curve. - Fast response time and 144Hz refresh rate make everything feel smoother. It's really hard to go back. - Editing photos, the colour gamut and accuracy out of the box are decent and certainly good enough for an amateur photographer like me. - Comes with all the cables you need for the full resolution and frame rate experience, just make sure your video card supports DisplayPort - Supports AMD free sync and also works with G-sync for Nvidia cards (GTX1060 in my case) Cons: - It's weird when you're sharing your screen on a call and everyone gets confused by the size and aspect ratio, same goes for full screen screen shots :) - Not every game supports the ultrawide format and finding the right compromise of resolution and black bars left and right can be tricky. - The default colour depth is only 8-bit and I am pretty sure I noticed that during my first photo editing session when colour transitions looked a bit rougher than I was used to. A quick online search revealed that the panel does actually support 10-bit depth but you need to force it through the video card (Nvidia in my case) driver. - The curve and aspect ration take some getting used to. Especially on a browser window, the curve threw me off and I kept missing information on either side since it was too much in my peripheral vision. By now, I am well used to it though. - Viewing angles are not great for someone coming from an IPS panel but they're decent for a VA panel. And since it's only me looking at it straight on, it's alright. - It does generate quite a bit of heat at the top and the bottom corners - might be an issue for stuffy (home) offices in the summer In short: You get a great monitor with plenty of space and features. The support for free and G-sync and the 144Hz refresh rate are tough to beat at this price!

ES el primer monitor que tengo en formato ultra ancho o Ultra wide y la verdad esta genial, lo uso como complemento en mi escritorio como pantalla principal ahora y es una delicia los colores para nada son feos o pobres o faltos de brillo como había leído en otras reseñas, es una chulada y mas todo lo demás el Freesync, los 144Hz, etc hacen de esta pantalla un verdadero disfrute y por el precio que aunque no es un regalo fue muy accesible en comparación a otras marcas con las mismas características. totalmente recomendado!! aah por cierto es súper fácil de instalar no hay que hacerse bolas con nada solo ensamblas el soporte le das vuelta un tornillo con lengüeta para darle vuelta y apretarlo y listo!

Excelente monitor para jugar a un precio muy asequible, los juegos se ven geniales y en mi caso muy fluidos con la tecnología FreeSync (AdaptativeSync) de AMD. Tuve que ajustar los colores de manera manual ya que los perfiles predeterminados no me agradaron mucho. Para el trabajo diario me gustó mucho, puedes tener dos ventanas en la misma pantalla con un tamaño que te permite trabajar de manera cómoda. Una excelente opción si lo que buscas es mayor comodidad para trabajar y una mejor experiencia para jugar. Cabe mencionar que no todos los juegos soportan el formato 21:9, pero aún así vale mucho la pena.
