AOC AGON AG405UXC - 40 Inch QHD Gaming Monitor, 144Hz, 1ms, 21:9, HDR400, Height Adjust, FreeSync, Gsync, PbP mode, USB-C 90w PD (3440 x 1440 144Hz, HDR400 HDMI 2.0 / DP 1.4 / USB-C / USB 3.2)

With all the negative reviews I was a little anxious as to how this monitor would turn out. I need not have worried. No dead pixels, fantastic picture out of the box (could do with some minor tweaking which I will get around to), gorgeous colours - this really is a fantastic monitor at the price point.Coming from a 1080p monitor with a TN panel, the step up to 1440p with an IPS panel is a big one. So too is the availability of 165hz refresh rate; I'd always been sceptical about the personal benefit I'd see from anything over 60, but it really is just like people say it is. Everything just feels better.I've not had a chance to give G-Sync a good workout just yet but I've got a very good feeling judging from the rest of this package, I'm going to be happy.It isn't a perfect monitor for sure; there is bleed in all 4 corners, but (at least on this one) it is very minor and I'd really have to go out of my way to even get a little bit worked up about it being there. It is such a non issue. Also, if you like plenty of scope to plug in every single console / PC / media device you own into this monitor at the same time, you are going to be disappointed as there are just two ports; Display Port and HDMI. I'm really struggling to pick any more meaningful faults with it though.With a great feature set and attractive pricing, I see no reason to pay extra for the ASUS or Acer alternatives.Edit: Several months on and I have to say this monitor has not disappointed. G-Sync is incredible; I now understand when people say they could never go back to a non G-Sync monitor after using it. Games look and feel sensational. Given the current price (around £650) there are monitors that outdo this one, but if you can get it for £500 or so, you will not regret this purchase.

This product completely blew me away. The quality is top-notch, and it’s packed with so many features that it feels like a flagship in its category. The OLED screen is absolutely gorgeous, vibrant and super immersive. I also love that it comes with all the cables you need right out of the box, so setup was a breeze. The built-in speakers were a pleasant surprise, they’re way louder and better than I expected for a monitor. Honestly, it feels like it’s worth twice the price.

I bought this monitor as I needed a single monitor which would connect to both my Dell XPS 15 work laptop (via usb-c dock) and to my gaming pc (directly via DP). It is replacing my old Asus Rog Swift 27", as it only had the one DP port.The below feedback is after 2 weeks of heavy use;Build quality feels very good - sturdy, and I am impressed with the range of movement (tilt, up/down, swivel) available. I am surprised to find that the monitor does not wobble at all from typing, as I am quite heavy handed with my typing.The stand has okay but definitely not outstanding cable management support. Not really a big issue because I have the monitor positioned relatively low (about 4" from the desk).There is a small extendable headphone arm on the right side of the monitor, however it seems unusable to me. Placing my Headset on it makes the monitor lean off to one side due to the weight, and I do not like how close the earcups sit to the panel. This is with quite a large headset, so this feature might work fine for you if you have lightweight headphones.The monitor includes a built-in usb hub, one slot of which can be configured to provide charge whilst the monitor is off. I use it for some of my peripherals, works well.The menu button itself feels sturdy and easy to reach, however actually using it to navigate the menu is unintuitive and feels a bit clumsy. This would not normally matter as I like to use software such as ControlMyMonitor.exe anyway, but a couple of important features do not seem to be present in it (controlling the OC, video source, and RGB's for example).Ultimately, a minor complaint. The only feature I bother using at all after the initial setup is swapping video source, which requires only a quick flick to the left. Swapping between my laptop and desktop this way is very fast and saves me a lot of hassle.The monitor has an effective deep sleep mode if I step away from my pc for an extended period of time, so I don't feel the need to physically turn it on/off on a regular basis.Onto the screen itself -The size is superb and at a normal viewing distance (arms length) I can't discern any blurriness of text or individual pixels.I'm sure it isn't perfect in terms of colours (I wouldn't know because I don't do any sort of colour sensitive work), but for me they feel vibrant with excellent darks.Games feel immersive (with barely a FPS drop when compared with my previous 2560x1440p monitor), and the screen estate is very comfortable for work.Gsync works nicely once I turned on the framerate OC (120hz). I feel this step was absolutely neccesary because 100hz felt awful to me, but if you are not currently used to 144hz you may not mind. I have kept an eye on the stability and heat output of the monitor following the OC, and it certainly is safe and stable so you may as well switch it on in any case.All games I have tried work at the full ultrawide resolution, worst case I've needed to implement an easily-googleable edit (replacing an .exe for example). A lack of game support is a relic of the past, ignore the nay sayers.The main drawback to an ultrawide is that movies/videos leave black bars at the sides, but this isn't anything that you can resolve by buying a different model. There are some browser extensions that can address this, but they have their own drawbacks.If black bars whilst watching video bothers you, ultrawides don't suit your needs.Overall very happy with it, good quality at this pricepoint. AOC have an excellent RMA and warranty, so I feel confident that I will get plenty of value out of this monitor for years to come.

It is excellent well built monitor. It is big but not too big for my desk which is only 65cm deep. It works in 120hz when connected through displayport what is very important to me as it is double speed of the standard 60hz. It can go up to 144hz but I do not use it at all. It only goes up to 100hz over HDMI. Personally I feel that there is not much blur like many people and reviewers complained about. It is big upgrade from my 32" Viewsonic monitor. There is way more space available on the desktop, colours can be set to pop out of the screen, menu is very comfortable to use, contrast level is good enough. I am pretty impressed with the quality of the picture and the feeling of smooth movement in 120hz. It works great so far. Also there is EU and UK power lead included and HDMI and DisplayPort cable as well. I definitey recommend this monitor to anybody who wants bigger screen than standard 32" 16:9 monitor - it is real solid upgrade. At the moment I feel that anything bigger would be just too much but if there was a 42" version I would probably buy it instead and upgrade the desk to 80cm depth.
