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 - a fantastic display
A great purchase even at its MSRP of 450.00. I'll run through the pros and cons.Pros-Adjustability – height, swivel, and tilt - the swivel was the only one that was too resistant, I couldn't swivel it without moving the feet of the base, even though it is capable of rotating a few degrees, but not a big deal for me.-Curvature – 1500R is a bit more aggressive than the usual 1800R (meaning, 1800mm or 1.8m radius) – for me this works great since the display is so wide on the sides that the more aggressive curvature works better to face the user at a more desirable angle.-Picture quality – to my everyman’s eye the pictures are fine if oversaturated a little bit. If anyone has the best OSD picture settings suggestions for this display, I’d love your input.-Adaptive Sync – with my RTX 2070 the G-Sync works flawlessly without any flickering or additional adjustments. The adaptive sync option was enabled out of the box for me.-144hz Refresh Rate – this is where the display shines for me, coupled with the adaptive sync feature. No more super annoying and horrible looking screen tears while gaming.-Viewing Angle – the side to side viewing angle is excellent, and with the curved surface area it’s even better, there’s no discernible off-axis desaturation for me.Cons-Design – personal preference completely, but I would have liked the design to be more “productivity” based, or more business-like. But the design is not horribly “gamer-y” either.-OSD – the controls are located toward the bottom right of the frame with five discrete buttons. They are poorly spaced so it’s difficult to distinguish by feel and are very clunky to operate.-Documentation – I wish the manual contained more information about what each specific setting does. There’s hardly any documentation included, other than the basic setup, which is practically useless.This is a fantastic display with all its wonderful features, especially at its price point. Just look at the list of pros vs cons. The pros are all the reasons you would choose to get a monitor of this kind.Now that I’ve experienced 21:9 I cannot go back to 16:9 configuration (as a very, very casual gamer). The ultra-wide orientation is also great for video editing. The only thing I would wish for is now for the monitor to get larger in size at a similar price point. Highly recommended.My SpecsRyzen 7 3700x32GB Corsair Vengeance 3200Hz RAMGigabyte RTX 2070Asus TUF X570

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)
