Review: Great Alternative To ASUS / Acer Offerings - 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.
Review: Excellent for both productivity and gaming - 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.

### ⭐⭐⭐⭐⭐ Nice monitor
*by A***W on 19 August 2018*

Lets get the negative stuff over and done with first: AOC forgot to place an instruction manual in the box. AOC also forgot to put an English cable needed to connect to the power brick, so i could not switch this monitor on to see if it worked. I had to go to Argos and pay for an American to English plug adapter, now these only cost £1.50p but it's not the point. The screen is also a finger print magnet, again AOC failed to provide anything to clean it with. Amazon sent this out in it's Original packaging without any protective boxing - no common sense what so ever, and they wonder why there is so many items damaged and RMA's.. Also the stand takes up a fare bit of space making the monitor a little close to the eyes. Now the positive: Games on this monitor look amazing. You will have to use the included displayport cable to get the full 144hz refresh rate. I have 8700k with EVGA 1070. I have test CS GO and i got no screen tearing or ghosting at all. I have also tested the HDR functionality using BF1 and it looks excellent, no washed out colours. There is an Acer curved 31.5 display just released that has a 1ms response time, i turned my nose up at this because the brightness on the acer only goes up to 300cdm2 where as this AOC monitor goes up to 400cdm2 making the HDR look far better. I no Arkham Knight is an old game but feck me does it look amazing on this display with all the settings maxed !! As for setting this monitor up go to youtube and search for TotallydubbedHD, and this guy shows how to set the previous version of this monitor up, the settings also work on this newer model. This model has the newer settings UI and is more intuitive than the previous version. Also looks cooler to :) I would recommend this monitor and have no regrets purchasing it. Please excuse the wonky distorted photo's, they were taken with my LG G6 smart phone but for some reason, all the camera's i own do not seem to be able to capture the screens curve in it's full glory.
